Mechanical Packing
THREE BASIC FACTORS assure long packing life and trouble-free service
1. MATERIALS used in the manufacture of mechanical packings are determined by the liquid being handled and the temperature at which it must be sealed.
2. DESIGN and CONSTRUCTION of the packing are determined by pressures and motions which are found in the equipment.
3. INSTALLATION and MAINTENANCE must be carried out by mechanics who understand that the time spent in applying packing properly will prove well spent in gaining longer, better packing service.
SELECTED ASBESTOS YARNS and FABRICS
All Johns-Manville Mechanical Packings are made from ma terials proved by long experience to be most satisfactory in the service for which they will be used.
The asbestos yam used in the production of J-M packings is high quality roving which has been mechanically spun or twisted to give it tensile strength. It is prepared in a wide range of grades, sizes, and plies, either plain, metallic or rein forced, to meet rigid specifications. From the mine to the user every step is carefully controlled.
These yams form pliable mineral fabrics, ropes, cords, tapes and tubings having high strength and resistance to chemicals and abrasion.
Unless otherwise indicated in descriptions of specific styles, the packings discussed in this catalog are made of commercial grade white asbestos yams. This represents an asbestos content of 75% to 80% by weight in the finished yam to meet A.S.T.M. standards. Some styles utilize even greater asbestos content.
Blue asbestos fiber is used in some packings. Yams made of blue fiber are more abrasive than white asbestos but provide necessary resistance to action of the most severe acids.
TEMPERATURE LIMITS OF ASBESTOS IN SERVICE
The service temperature limits of asbestos vary depending on whether the heat in the line bears directly on the asbestos, is somewhat diverted, or is actually sepa* rated as In the case of most stuffing boxes. A general table for guidance' follows:

ASSURES LONGER PACKING SERVICE
Experts find this selection procedure gives them the right packing for the job
Selecting the right packing depends upon the following factors:
Shaft size, in, Shaft speed, rpm. Pressure on the stuffing box, psi. Fluid temperature on the stuffing box, F. pH of the fluid to be sealed.
Step 1: Use of PV Tabic -- Each packing construction (material, braid pattern and lubrication) has its theo retical limit of strength in service, which can be corre lated with the "PV function." The latter can be defined as the product of the pressure to be sealed at the stuff ing box in psi, times the shaft speed in feet per minute.
Let us consult the table below to find out what packing to use for a boiler feed-pump having a 2Vi-in. shaft rotating at 3,600 rpm. -- the pressure to be sealed being

It is suggested that pressure-balanced mechanical seals be used for PV values of 1.250,000 or above.
350 psi., and the fluid temperature about 430 F. The PV value would be 350 X ~l/2 X n/12 X 3,600, which equals 524,250. From this Table, we see that a packing of twisted lead rings alternated with Loklube rings would be a logical selection.
Step 2: Use of Temperature Limits-- In the second step, you eliminate certain packings because of tem perature restrictions.
Step 3- Use of the pH Limitations -- In the third step, you eliminate those packings that are unsuitable for the degree of acidity or alkalinity of the particular' liquid.
Tentative pH ranges for various packing materials (basic fiber plus lubrication) are given below:

Theory Behind Packing Performance
A set of packing installed in a stuffing box generates a resistance' to the rotating' shaft. Thus, work must be done to turn the shaft. When you perform work, you generate heat. For a typical stuffing box, consider the following items:
W = work necessary to turn the shaft, ft.-lb./min. P = fluid pressure on the stuffing box, psi. L = depth of the stuffing box, in. d = shaft diameter, in. V = shaft speed, ft./min. / " coefficient of friction, dimensionless. Q = heat expressed in BTU/min.
The work required to turn the shaft is: W = PLdVf
(1)
To change work to heat, we use the first law of thermo
dynamics, which states Q = W/J, where J -- mechani
cal equivalent of heat, 778 ft.-lb./BTU. Thus, the heat
generated in a stuffing box can be stated as:
Q = PLdVf/1
(2)
Equation (2) shows that as pressure, stuffing box size, shaft diameter, shaft speed and coefficient of friction increase, heat problems increase accordingly. This com pound effect requires adequate lubrication to compen
sate for this increase in heat.
Why Packings Fail
The most commcjn cause of packing failure is lack of lubrication. Why? When you turn off the lubrication, you generate heat. The initial impregnation put in by the manufacturer is intended to serve as a primary seal ant for start-up and break-in period, and to prevent shaft scoring during start-up. After start-up lubrication must be provided to insure long packing life.
The second most common cause of packing failure is poor initial installation. Many maintenance men try to jam the packings into the packing box to pre\ ent leak age on start-up. Proper packing installation and bolt take-up on the gland will prevent packing failures.
Some tips on trouble-shooting packing failures are given on page 43.

Johns-Manville LOKLUBE Packings are designed for general service in a wide range of applications. New improved ingredients and production methods have been incorporated to increase performance levels and packing life, thereby reducing the frequency of gland takeups and repacking. This assures positive, demon strable savings in packing costs, down-time and labor. J-M LOKLUBE Packings are specifically designed to provide extra efficiency in performing particular operations.
J-M LOKLUBE lubricants are special-purpose types, developed particularly for pump packings. Their per formance and service life are far superior to lubri cants used by the Industry in general service pack ings. Their unusual heat resistance (up to 500F) in sures they remain stable at high temperatures, so that the combination of heat and pressure does not force them out of the packings.
Ordinary lubricants, which melt at 160-190F, "ooze" out--either in routine operations, or if the gland has been tightened ton much. For instance, when new packings are installed, and adequate leakage has been allowed for during the hreak-in period, another main tenance man often follows and tightens the gland oxcessi'-eh' to stop the leakage The temperature rises-- the lubricant melts and is forced cut of the packing, which shrinks and fails.
J-M LOKLUBE Packings retain their full lubrication and continue their sealing and protective functions even when operating temperatures are higher than normal. This means less friction, longer packing life, fewer repacks and less shaft/sleeve wear.
Johns-Manville has' developed an entirely new-, dif ferent and inventive production method which pre lubricates each asbestos strand prior to braiding! The lubricant is locked integrally into the structure of the packing, insuring a constant supply of lubricant throughout the life of the packing.
Most packings are lubricated by dipping the finished product into the lubricant. In operation, the lubri cant washes out, leaving the bare strands to seal the shaft. This leads to overheating, premature packing failure and shaft wear.
Long after lubricants in ordinary packings have washed away, J-M LOKLUBE Packings retain their efficiency, preventing overheating and wear on both the shaft and the packing. You save on the costs of the packings, labor, downtime and shaft /sleeve re placement.
Johns-Manville Interlocked Construction in all LOKLUBE Packings uses only one or two strands in the center to "lead" the braiding process. This pro duces a firm, long-wearing packing. Lubricant loss re mains at a minimum, reducing friction and shaft wear --less adjustment and longer life before repacking.
Some packings use multiple single strands of asbes tos in the center to build up the required bulk to make the correct size. The result is a weaker, less resilient structure which tends to ravel in installa tion, requires more compression to obtain a seal, and needs more frequent adjustment. It packs down, squeezing out the lubricant, causing faster wear.
J-M LOKLUBE Packings are designed for general service media ranges--pH from 4 to 10. This permits handling a broad range of fluids --hot and cold water, brine, oils, weak acids, weak caustics, etc. This versatility allows you to standardize on J-M LOKLUBE Packings and reduce your inventory requirements.

J-M LOKLUBE Packings are even and smooth. They fit into stuffing boxes without preliminary pounding to size. Easy to cut, easy to pack without forcing or keystoning, they require less compres sion and less gland take-up to maintain a seal.
IMPORTANT: Use normal, good installation prac tices. Remove all old packing, clean the stuffing box, use the right packing size, cut rings properly, install one ring at a time. Pay particular attention to the following step: After the last ring is in stalled, take up the bolts finger-tight. Start the pump and take up the bolts until the leakage is decreased to an acceptable minimum. Allow pack ing to leak freely when starting up; allowing gen erous leakage during the first hour of operation results in better break-in. Take up gradually on the bolts until the leakage is tolerable. Never try to stop leakage entirely.

Johns-Manville
J-M Interlocked Asbestos Packing is an extremely versatile and adaptable packing that delivers outstanding perform ance and is highly recommended for selection as a general service style for most plants. It is suitable for applications on both centrifugal and re ciprocating pumps, agitators, valves, expansion joints and in grooves. A unique and distinctive method of braiding asbestos yam, exclusive with Johns-Manville, is employed in the con struction of Interlocked Packing. There are no jackets to wear through or come apart, and no plaits which might become loose. All the long fiber asbestos yams extend back into the body of the packing and axe strongly inter locked to form a solid integral structure that cannot ravel or come apart in service. Interlocked Packing is unusually flexible and resilient. And because it is braided square rather than being pressed into shape, it presents a full surface contact across the entire width of the ring, thus it provides a tight seal with mini mum gland pressure and take up. Also its inner compress ible structure offers good recovery to original dimensions.
STYLES AND FORMS
J-M Interlocked Packing is made in a variety of styles to meet a wide range of operating conditions. All of these styles have the same interlocked braided construction but are made with various types of impregnation and yams. The styles described on these pages are made of Asbestos yams, with or without wire reinforcements.
j-M Zuu Interlocked Packing is an outstanding general G service style. It will handle hot water, cold water, brine, oils, weak caustics and acids, solvents and a wide variety of materials designated G in the Chemi cal Table. It is an excellent packing for centrifugal pumps, posi tive displacement pumps, expansion joints and valve stems. J-M 255 has proved extremely popular with mainte nance engineers because it has demonstrated unusual ability to handle almost any packing requirement.With a stock of J-M 255 on hand, the maintenance man is assured he will be able to handle almost any situation, including many appLcations for which special pack ings are often specified. Actually, J-M 255 can be con sidered an excellent universal packing to put in any service. Unless some special reason or condition exists, it can be counted on to work successfully.

Johns- Manville
Johns-Manville produces a variety of packings braided from select plant fibers. They are suitable for sealing rods, or outside packed plungers of reciprocating pumps, as well as accumulators, plungers and rams on other hydraulic equipment handling cold water.
Temperature limits will range, depending on fiber selec tion, up to 200 F for water or mild aqueous solutions. They are carefully lubricated to provide good sealability and low coefficient of friction. They are especially recom mended for applications on brass and bronze shafts.
J-M Navalon Packings, described below, are constructed of ramie rovings. A maximum amount of lubricant is ab sorbed by these fibers. Ramie fibers have excellent strength which improves with wetting. Also they are extremely stable and will not swell or expand in service as will flax.
Navalon Packings are impregnated with lubricants de signed to improve temperature resistance. These packings can be identified by the blue-colored center strand.
J-M Flax Packings should be used where the characteristic of some swell or expansion in service is not objectionable. The Flax Packings described below contain no impregna tion that will become rancid or cause chemical reactions to break down fibers. The lubricants are compounded for working temperature limits of 100 F.
f

J-M Thermocore Packings are designed for excellent heat resistance, and maximum adaptability to effect sealing un der least compression. The construction comprises one or more jackets of asbestos yam braided over cores, either plastic or asbestos.
J-M Thermocore is recommended specifically for valve stems. Some styles will handle service lines with tempera tures ranging to 1200 F.
Braid-over-asbestos-core types result in the softest and most adaptable of packings. These styles axe recommended for valve stems, slowly moving shafts, or other mechanisms where clearances are so wide as to require a material which will fill, the stuffing box-and readily adapt and com pensate so as to seal under pressure. The Rajah Packings are typical of this construction.
Styles constructed with plastic cores are designed for extremely high temperature and high pressure service con ditions in valves. The inert core provides stability and minimum volume loss under temperatures to 1200 F. Low stem friction is another feature. Sizes over %" have 2 oi more jackets, depending on size.
Styles made with metallic mesh cores are recommended for shafts having eccentric motion. The cores are designed to offer high recovery characteristics which enable these styles to follow off center shaft movements and still main tain maximum sealability. These styles are furnished in sets only and are described in the "Special Packing Sets" section.
Styles embodying a heavy grease type core are designed to handle high centrifugal shaft speeds where lubrication is a problem, as in gasoline pumps or pumps having no facilities for supplemental lubrication.
J-M Thermocore Packing is designed for service in G valves handling steam at line temperatures up to 1000 F and handling other media designated G and S. Braid-over-core Inconel wire inserted 95/98% asbes tos yam jackets over-a plastic core.

j-M ,53/ Thermocore Packing is designed to handle fluids O
under extreme service conditions found in power plants, and the petroleum, petro-chemical and chemi cal industries. It is a braid-over-core construction con sisting of Inconel wire-inserted 95/98% yam jackets over a plastic core. Sizes Vi inch and up are furnished with a plastic core of white asbestos and graphite; sizes up to but not including Vi inch are furnished with blue African-asbestos yam graphite-treated core. J-M 397 has a graphite finish and J-M corrosion in hibitor (to protect valve stems after hydrostatic test and before they are placed in service).
Because of the inert qualities of the asbestos, Inconel wire and graphite, J-M 397 can be used in valves handling a wide range of petroleum products and chemicals. It will handle all chemicals designated G and S in the tables, at pressures up to 5000 psi in usual designs for valve stuffing boxes. Chemically, it will handle materials designated P and F as well, if the packing does not enter the medium handled. Depend ing on concentration of such solutions, it will also handle acids and caustics designated T and C.
Because J-M 397 is almost entirely inorganic, it main tains its stability even in valves where line tempera tures run up to 1200 F.
This packing contains no component which would harden under high or low temperature conditions, or oil lubricant that could squeeze out of the packing under gland pressure.
J-M 397 meets MIL-P-17303C, Class II, Type E, Symbol 1111. Pressures to 5000 psi; line temperatures to 1200 F.
J-M 6 Rajah Packing is made in a square cross-section of G
the braid-over-core construction. The core consists of soft twisted asbestos and the jacket is braided from white asbestos yams. The packing is not lubricated with an oil but is treated with a light surface coat of natural and buna-S rubbers. Has a graphite finish.
Because it has no oil content, J-M 6 Rajah can be used at temperatures higher than J-M 223. It is a soft, adaptable, inert packing suitable for service up to 750 F line temperature in valves. It can be used in other services where the conditions correspond to valve stem service. Pressures to 300 psi; line temperatures to 750 F.
2J-M Rajah Packing is made exactly the same as J-M 6 G
but in a round cross-section and should be employed where the most adaptable of all braided packings is required. It can be deformed to fit packing spaces smaller than the nominal size or spaces larger than the nominal size of the packing. For best sealability, J-M 2 Rajah should have packing space the same width as the diameter of the packing. Has a graphite finish. Pressures to 300 psi; line temperatures to 750 F.
232j-M Packing is furnished only in rings and sets. It is described on page 27
j-Mday Thermocore Packing is exactly the same as J-M Q 398 except that there is no wire reinforcement in the yams. It can be used where a slightly softer packing is required or where shaft motion makes a wire re inforcement undesirable.
J-M 399 has a mica finish, and contains the J-M cor rosion inhibitor.
J-M 399 is noted for its sealabilitv and adaptability under high temperature conditions. Pressures to 4000 psi; line temperatures to 900 F.

Johns-Manville
Johns-Manville produces a variety of soft, highly adapt able asbestos packings of braided construction. Each of the styles described below has been providing excellent service for more than fifty years,
These packings are made by braiding tubular jackets of asbestos yarn, employing either braid-over-braid construc tion, or braid over a soft asbestos core. They are made up round, then calendered to form a square cross-section.
Braid-over-braid types result in the strongest of all braided constructions. This strength has made it popular for valve stems where high pressures are encountered. The Mogul and Jewett Packings are typical of this form. These braid-over-braid types can also be used for slow moving shafts.
The braid over asbestos types, including the Rajah styles, are described in the Thermocpre.section, page 16.
223J-M Mogul Packing has almost countless uses where G a soft pliable packing without rubber is required. The expression "Graphited Asbestos Packing" generally applies to J-M 223 Mogul. Popular with the plumbing trade, it is widely used on valve stems and low pres sure steam lines. It can be used on slowly turning or oscillating shafts. J-M 223 Mogul is made by braiding white asbestos yams, braid-over-braid to the proper size, and lubri cating with a light petroleum base oil. It is then calendered to a square cross-section. Has a graphite finish. Pressures to 300 psi; temperatures to 600 F. Speeds to 1750 rpm. PV limit = 400,000; pH range = 10 to 4.
J-M 222 Mogul Packing is suggested for low pressure gen- G
eral service, especially where packing space is small. The round shape is often used where tolerances are too wide, or the packing space too varied to accept square designs. Easily deformed, it compresses read ily to form rings of desired dimensions. J-M 222 Mogul will handle low pressure steam and is suitable for general service on valve stems, and reciprocating or oscillating rods and shafts operating at slow speeds. It is made by braiding commercial grade white as bestos yams to the proper size, and lubricating with a light petroleum base oil. Has a graphite finish. Pressures to 300 psi; temperatures to 600 F.
Speeds to 1750 rpm. PV limit = 400,000, pH range = 10 to 4.
2020J-M Braided Packing is made of special white as-c bestos yams, braid-over-braid and squared.

j-M Rubber and Suck Packing
handles cold water, hot water to 250 F. compensates for swelling seals against off-center motion
Johns-Manville rubber and duck packings are recommended far use against hot water to 250 F and low pressure steam. Some styles, however, may also be used for other media such as light oils, ammonia, cold water and light aqueous solutions in reciprocating and slow rotary service.
They are made of high quality duck which is laminated and bonded with specially compounded rubbers to prevent leakage
through the packing. This provides a strong stable material which is then lubricated with mineral oil and graphited. The natural resiliency of this type of construction compensates for swelling tendencies in hot water service and also aids in sealing off-center motions.
271j-M Cross Diagonal Rod Packing is the best packing for cold and hot G
water service on water end of reciprocating pumps. It is excellent for
boiler feed water service and will withstand the action of caustic treat
ments in water.
'
The rubber and duck plies run diagonally to the rod so as to allow natural swell of the packing without excessive pressure against the rod. This results in less rod wear, better sealing, longer packing life. Lubri cant is mineral oil. Has a graphite finish.
Temperatures to 250 F.
171J-M Ouro Rod Packing is a good, dependable material for service G against low pressure hot or cold water and mild aqueous solutions. It will give satisfactory service on reciprocating rods, valve stems and outside-packed pistons and valve rods on many types of recipro cating engines and pumps.

J-M Cumpace Packing Sets
low friction, efficient sealing, under severe operating conditions
J-M Cumpac Packing Sets are asbestos packings with a unique cross-section. They are designed to give O.D. and rod or shaft sealing, without excessive interference through follower pressure. Gland pressure seats each ring's flat section firmly in the stuffing box. This leaves the flexible lips free to seal with minimum friction. The special cross-section also permits more rings in a given stuffing box depth, resulting in greater sealing effectiveness. A minimum set consists of 3 center rings and a header ring. A follower ring is desirable when depth permits. For maximum sealability, 5 center rings with header and follower are required.
W* 40 I Cumpac Packing is intended for service on reciprocat G ing, oscillating or rotary shafts. J-M 237 is formed from a base stock of commercial grade white asbestos yarns in a dense braid-over-braid structure. It is further strengthened by a neoprene base compound and has a graphite finish. Hot moulded to density for serv ices to 1500 psi. Supplied solid or split. Please specity when ordering. Pressure to 500 psi; temperatures to 500 F.
J-M Conepac Packing Sets
Automatic low-friction sealing, without frequent gland adjustment
J-M Conepac Sets are made of rings in the conventional 45 degree diagonal sections, with or without header and follower adaptors. Although some stuffing boxes are so designed that adaptors are not needed, flat-end stuffing boxes would always require adaptors.
J-M `tU Conepac Packing is a general service packing used in G valves and also in slow speed reciprocating or rotary service. It is made of commercial grade, white asbestos, coppei wire inserted yams, braided over a lead-ribbon core, then formed to the Conepac shape. It is lubricated with a petro leum base lubricant and graphited. Split rings furnished. Pressures to 1500 psi, temperatures to 500 F.
236 JM 397 Cumpac Soot Blower Packing is especially recom-
mended for Soot Blower service and is furnished to fit ali
popular Soot Blower sizes.
Q
These two soot-blower packing sets withstand the severe, demanding service requirements of today's power plants-- whether for use with oil, gas, coal (or interchangeably) as fuel. J-M Research has developed these packings to save money --in installation, maintenance and service life, whether soot-blowers are movable or stationary. The dis tinctive--actually unique--design of these packing rings-- J-M Cumpac--provides both O.D. and shaft, rod or lance sealing without excessive pressure. The flat section seats firmly in the stuffing box, leaving the flexible lips free to seal with minimum friction, even against slight off-center or reciprocating motion.

J-M Groove Packing is designed for use as door or cover seals on furnaces, ovens, filters, vacuum tanks, and pres sure vessels such as autoclaves. Styles are available for grooved or flat-faced applications on door or flange whether the seal is effected by mechanical pressure of door against flange or by internal pressure forcing the packing outward against the door. Some industrial oven door de signs provide a groove in the body of the oven to hold packing against which the flat face of the door operates; some are designed with groove in the door so that packing seals against the flat metal flange of the opening.
To meet the separate sealing needs of the many available door and hatch design*, -J-M offers several packing styles, in varying densities, and treated to handle various internal media. Some are moulded under heat and pressure from asbestos and compounds. Asbestos types are either braided, folded, or fabric styles formed over resilient non hardening cores. Available in square and rectangular cross-section.
Extruded styles of special compounds, are available on application.

Thermo-Pac* Rope
general-purpose asbestos and refractory rope with temperature ranges from minus 400Fto plus 2700F
J-M Thermo-Pac Twisted Ropes are recommended for emergency packing and gasketing where other materials are not available, or where shape or condition of the equip ment will not allow the use of less pliable, less adaptable materials. They are suitable as caulking or filling mate rials where high temperatures or other conditions require an inert filler. They are recommended for confined areas protected from abrasion or tensile stress. These ropes are extremely versatile in that size can be re duced or increased-- simply by.-separating the strands or building up thickness by twisting several together.

J-M Twisted Asbestos Wick styles are soft, easily handled, highly heat resistant materials used as general utility and emergency packing, and in gasketing and caulking serv ices. Wick is especially suited for small packing spaces.
It is made by twisting together one or more strands of rov ing or felted strips of asbestos. Individual strands may be untwisted and used separately. Or, two or more lengths can be twisted together to provide any greater thickness.
J-M Asbestos Wick is employed as an expansion joint in the masonry construction of furnaces, and as a seal around hot pipes passing through masonry. In the Iron and Steel Industry, Asbestos Wick serves to prevent runout at dam aged or eroded portions of metal moulds and stools, to seal joints in sand moulds, and in hot topping.
In light metal constructions such as domestic heaters, wick serves as a packing in grooves pressed into metal shells.
For general maintenance work, J-M Wick will serve as gasketing on light, rough or uneven flanges where a con ventional gasket could not be used.
J-M 4lou Wick is the most popular Commercial Grade O asbestos twisted wick in a stranded construction. It differs from J-M Thermo-Pac 500 (a single-ply wick). It is made of a number of rovings for greater strength and density. Many manufacturers use it as a groove packing in light metal construction; it is also widely used as a general seal in the steel industry. For service to 500 F.

J-M Gasketing Tapes are soft, resilient, versatile materials recommended for many services where mechanical or economical reasons preclude the use of pre-formed gasket styles. Some typical applications of Gasketing Tapes are: in light metal flanges in oven construction; between struc tural sections of bridges; on marine or aircraft equipment, and on oil refinery bubble trays.
They are particularly suitable where the service may not be critical enough to justify the cost of gaskets, the open ing flange too large and irregular for a gasket, or the in stallation is such that it is impossible to install a gasket. They also serve effectively where only light pressure can be applied against the gasket.
Gasketing Tapes are not to be used where a complete seal of positive internal pressure is needed. For this, a cut or metallic gasket is required. If a gasket cannot be furnished or applied, a tape assembly may be used but with the un derstanding that there may be some leakage.
The commonly used asbestos tapes are all made of Com mercial Grade (75/80% pure) asbestos for service to 500 F. For higher temperature service, available on special order, Styles 121, 122, 131 and 132 are made in Under writers Grade, AA (90/94% asbestos --to 600 F), AAA (95/98% asbestos -- to 850 F) and AAAA Grade (99/100% asbestos --to 1000 F). Example: J-M 122 -- AAAA Grade.
j m 122 Gasketing Tape is the most popular woven tape G
for long term sealing of low pressure gases. Contain ing no compound, it has a wide range of applications in services handling hot, dry gases.
J-M 122 is a plain woven tape, made from yams of commercial grade, white asbestos. It contains no com pound, cement or wire.

Johns-Manville Tadpole Tapes are designed to serve as gasketing on light metal flanges or where limited bolting force is available, and the packing must conform to uneven or unequal surfaces . . . where equipment types and de signs do not permit use of endless gaskets or flat gasketing tape. Because of their softness and resilience, they adapt readily to irregularities, and are particularly popular where doors come to rest on the bulb of the Tadpole. They are easily installed by riveting, bolting, or by metal straps. The effect is that of a groove packing without the neces sity of providing a groove, or of a high temperature "O" Ring, held in place by the fabric tail assembly. These tapes offer long-lasting efficiency because they do not harden at high temperature. However,jap. Tadpole Tape is guaran teed to seal positive internal pressure.
Tadpole Packing is made by wrapping a core with asbestos cloth cover. The edges of the cloth are stitched or ce mented together to form a tail structure. Johns-Manville Tadpole Tapes are made in: Commercial Grade, 90/94% asbestos, and 95/98% asbestos. All three grades are avail able plain or wire inserted, in soft, medium or dense con structions. Special compounds can be applied to the cover cloth.
f
Note: If the Tadpole Tape is to be assembled with the tail tangential to the bulb, the "assem bled" overall dimension should be increased by the radius of the bulb, to arrive at the ordering description. Otherwise the tail may be too short for installation.
I/dJ-M Tadpole Tape is the basic Tadpole construction
and was designed for steam service at constant tem
peratures to 250 F. At higher temperatures up to
500 F the compound treatment becomes progressively harder. The asbestos itself is not affected.

J~M Tadpole Tapes (continued)
METAL MESH CORE TADPOLES
Metal Mesh Core Tadpoles are the softest of all Tad poles, and have highest rate of recovery and greatest temperature resistance. Certain styles are unaffected by constant temperatures to 2000 F.
Metal Mesh Core Tadpoles were originally developed as firewall seals on aircraft. They will withstand a 2000 F temperature for 15 minutes without permitting the passage of flame. _
Aj-M 15 0-12 Tadpole Tape will compress 403 of its c
bulb diameter with a load of 10 to 14 lbs. per running inch--and will recover 90S of its original diameter. J-M 150-12A consists of an Inconel Mesh core with a cover cloth of 90/94% pure asbestos yams, and Inconel wire. This cover has silicone rubber inside, a neoprene base flameproof treatment and a reflective aluminum finish outside. The tail is stitched with asbestos thread. For constant temperatures to 600 F.
Aj-h 150-13 is the same as 150-12A except the as- G bestos cloth cover contains no wire reinforcement and is therefore softer and more adaptable. For constant temperatures to 600 F.
Aj-m 151-18 offers good sealability because of a foil S
wrapping over the core. It consists of an Inconel mesh core wrapped with metal foil and covered with cloth of 90/94% asbestos yam having Inconel wire reinforcement in each yam. The cover is treated with a flameproof compound having a neoprene base. It has a reflective aluminum finish. The tail plies are stitched with asbestos thread. For temperatures to 4 00 F,
J-M IDU'IUA is the lowest priced of the mesh core S
types. It may be used where constant temperatures are not high, but the exceptional resiliency of the mesh core is desired. J-M 150-10A consists of an Inconel mesh core covered with cloth of Inconel wire inserted yams of 90/94% pure asbestos. It has a flameproof compound finish.
For temperatures to 350 F.
15 0-15Aj-m is recommended where there is move- T ment of the mating metal flange surfaces. It has an Inconel mesh core and is covered with a cloth of 90/94% pure asbestos yarns, and treated with Teflon suspensoid which reduces friction. The tail plies are fixed with asbestos stitching. For service against any media except metallic sodium and potassium. For temperatures to 500 F.
150-14Aj-m is the same as 150-15A except that the T cloth contains an Inconel wire reinforcement for greater strength and durability.
150-17Aj-m is suitable for sealing gases and most G
aqueous solutions except those which attack silicone. It consists of an InconeTmesh core with a cover cloth of 90/94% asbestos yam. It has a flameproof treatment and an exterior finish of silicone rubber for good sealability. For constant temperatures to 450 F.
15 Aj-m 0-20 is the lightest in weight, easiest to com- S press, and has highest recovery factor of any Tadpole structure. It consists of an Inconel mesh core with a cover con sisting of neoprene base flameproof compound rein forced with Inconel mesh. For constant temperatures to 350 F.
160-21Aj-m is the Tadpole that will withstand high- G est operating temperatures. It is made of a core containing Inconel mesh, foil and a soft refractory fiber. The cover consists entirely of fine Inconel wires braided over the core. For constant temperatures to 1000 F; intermittent to 2000 F.

Johns-Manville Mechanical Seals for leak-proof service on rotary shafts
Simple design -- easy to install and maintain
The J-M Mechanical Seal provides a new, simple, eco nomical, general-purpose seal which combines the best features of both mechanical seals and stuffing-box expe rience and practice. It is the engineer's solution to the problem of positively sealing pumps and mixers. De signed to fit easily into standard stuffing-boxes, it pro vides clean, leak-proof sealing. Because of its simple and efficient construction, compared with most other mechanical seals, it gives long, trouble-free, "set-itforget-it" operation.
J-M Mechanical Seals are readily available from stock in standard sizes and construction. Only two compo nents -- the "O" Rings and End Seals -- are variable from standard materials. This simplifies selection, installation and allows a wide variety of uses. This simplification makes it ideal for standardization of your sealing requirements and ordering procedures. Your J-M Representative will be glad to help you select just the right combination for your sealing requirements.

Die Formed Rings
Method of Operation
The sealing principle of the J-M MECHANICAL SEAL is common to the full range of standard sizes available, i.e., for shafts from 5" to 95" in diameter and is diagrammatically presented in the accompanying illustration.
The Cland Sleeve (I), which has a replaceable End Seal in halves (2) held in position by the Gland Nut (3), is fitted into the stuffing box and it is sealed by the 'O' Ring (4). An Anti-rotation Stud (5) fitted into the stuffing box passes between two guide lugs (6) on the Gland Sleeve.
The whole assembly is allowed to move axially within the stuffing box according to the pressure exerted by adjustable Springs (7) acting through the Yoke Plate (8) on the Gland Nut. These springs force the End Seal against the Cone (9), which rotates with the shaft and is sealed by the *0' Ring (10), to provide the running seal.
Special Sealing Requirements
J-M Mechanical Seals, in stock, cover a broad standard range of sizes and materials suitable for most uses. They are available for immediate shipment. For special sealing requirements, in size or materials, consult your J-M Representative.
J-M Die Formed Rings
J-M Die Formed Packing Rings are custom made to closely con trolled dimensions to provide a mechanically perfect fit. Grouped into two tolerance ranges--standard and close tolerance--to fit specific equipment needs, they assure easy assembly and max imum sealability.
These precision-made rings are available in virtually any required size and flange width, in many styles and compositions, and are lubricated to meet the needs of specific service conditions.

HELPFUL SUGGESTIONS ON HANDLING PACKINGS
How to Get the Best
Results from Packings
There are foilr main factors that influence the life and performance of packings in service. Give careful atten tion to all these factors and the most satisfactory service will be assured.
The best way to cut packing rings is to cut them on a mandrel the same diameter as the shaft in the stuffing box area. If there is no shaft wear, they can
Quality of Packing Used--Packing costs far less than the labor and lost production time of re-packing. The use of poor quality packing can sometimes result in dam age to equipment. The best quality packing is the cheapest.
The Right style for the Service-The recommendations on pages 4 and 5 are based on Johns-Manville's re search plus practical field service. For special cases, consult your J-M Packing Distributor or J-M Sales Engineer.
Mechanical Condition of Equipment--It pays to use high quality' equipment that is properly maintained. If bearings, shafts, sleeves or guides are in bad condi tion, the result is poor sealing, short packing life.
Packing Installation and Lubrication-Properly installed and lubricated, packings help equipment operate efficiently. The suggestions below have been found helpful.
HOW TO PACK STUFFING BOXES
Pumps and Agitators
1. Remove all old packing from the stuffing box. Clean the box and shaft thoroughly and examine shaft for wear or scoring. Replace shaft or sleeve if wear is excessive. Check bearing by lifting shaft up and down; do not expect the packing to act as a bearing.
2. Use the right size of coil packing, to be sure the pack
ing will fit and can compensate for shaft wear, if any. To determine the correct coil packing size, measure the diameter of the shaft (inside the stuffing box area if possible) and then measure the inside diameter of the stuffing box itself (to give you the O.D.' of the ring). Subtract the I.D. measurement (the shaft di ameter) from the O.D. measurement and divide by two. The result is the required size. Other than special precision molded packings, all standard shaft packings are made up in increments of hV from the smallest size available and up. For most applications, if the calculated size figures under a 16th of an inch, it ;s generally best to use the next size greater. Thus, if the shaft measures 21,'" and the inside of the stuffing box 3V, the size of coil packing to use would be rather than }'u".
3. Cut packing into rines. Never wind packing into a
stuffing box. For pumps and agitators cut rings with a butt ("square' joint, it is easier and you can do a better job.
be cut on the shaft itself outside the stuffing box if there is room. Hold the coil packing tightly and firmly on the mandrel but do not stretch it excessively. Cut the ring and try it in the stuffing box to make certain that it fills the packing space properly, with no gap in the joint at the O.D. of the ring.
Each successive ring can be cut in the same manner, or the first ring can be used as a master from which the balance of the rings are cut. If the rings are cut on a flat surface be certain that the side of the master ring, and not the O.D. or I.D. surface is laid on the rings to be cut; this is necessary so that the slight bevel at the ends of the rings be reproduced. Remem ber that the O.D. circumference of the ring is greater than the I.D. circumference.
4. To cut rings from a packing that is unusually soft or
that has a tendency to fray excessively, some me chanics apply a small piece of tape at the point where the cut is to be made, then cut through the tape. If the tape is thin, it can be left right on the ring.
5. Install one ring at a time. Make sure it is clean and
has not picked up any dirt in handling before installing it. If clean oil is available it is well to lubricate each ring thoroughly; some mechanics also lubricate the shaft and the inside of the stuffing box.
Joints of successive rings should be staggered and be kept at least 90 apart. Each individual ring should be firmly seated with a tamping tool. When enough rings have been individually seated so the nose of the follower will reach them, the individual tamping should be supplemented by the follower. Never de pend on the follower entirely to seat a set of rings properly--this practice will jam the last rings installed but leave the front rings loose in the box. The result is excessive and rapid wear of rear rings; erratic packing performance; sometimes, twisting and tearing of the front rings because they are loose in the stuffing box.
6. After last ring is installed, take up bolts finger tight.
Start the pump, and take up bolts until leakage is
detreased to no more than 2 drops per second. Stop
ping leakage entirely at this point will cause the pack
ing to bum up.
FBW-
4-3
7. Allow packing to leak freely when starting up a newly
packed pump. Excessive leakage during the first hour of operation will result in a better packing job over a longer period of time. Take up gradually on the follower as the packing seats until the leakage is about 2 drops per second on a 1" shaft at 3600 RPM. Allow proportionately more as the shaft size increases. For speeds lower than 3600 RPM, less leakage is permis sible. It will take about one working day to break in a set of packing to a point where the leakage is stabilized at a uniform acceptable rate. Never try to stop leakage entirely.
8. If at all possible, provide through a lantern ring, means of lubricating the shaft and packing by supply ing grease, oil, water, or the liquid handled in the pump. Fittings for this, purpose are standard on most pumps.
ting other rings on a flat surface to insure that the additional rings are cut precisely at the correct angle. <
2. Bring the follower down on the packing to the point vkhere heavy resistance to wrenching is felt. During this time turn valve stem back and forth to determine ease of turning. Do not wrench down to the point where the stem won't turn.
3. After the valve has been on the line a day or so, even if no leakage exists, the follower should be tightened slightly. If it is leaking at all, tighten the follower until there is no leakage.
TROUBLE SHOOTING
PACKING FAILURES
Carefullyexamine packih'g removed from a stuffing box, as it often gives clues to the condition of the equipment and may be the means of solving packing problems. The fol lowing clues and possible troubles were found by exam ining sets of packing which had seen service:
9. If the stuffing box has a lantern ring, make sure the
lantern ring, as installed, is slightly behind the lubri cant fitting so it will move under the fitting as follower pressure is applied.
10. Replace packing when leakage cannot be controlled
by further take-up on the follower.
Valves and Expansion Joints
The function of a Valve Stem Packing is like a gasket function rather than pump packing, which must both seal and carry lubricant for a turning shaft. Valve Stem Pack ings must provide a dense structure that will not permit movement of the liquid or gas through the body of the packing itself. The packing under follower pressure must be able to flow sufficiently to seal along the stem and along the stuffing box wall. By maintaining low friction, it will permit easy movement of the stem. To pack valves:
1. Carefully perform all the operations outlined under steps 1, 2, 3, 4 and 5, as given for pumps and agitators. Rings used on valves and expansion joints should be cut with a skive joint.
Clue: Excessive reductions in the cross-section of the packing directly beneath the rod, shaft or plunger. Possible trouble: Low bearings with shaft or rod riding on packing. In service early leakage occurs around the top of the shaft or rod.
Clue: Excessive reduction in the thickness of the pack ing directly over or on either side of rod or shaft. Possible trouble-. Rod or plunger out of alignment and in the case of the rod or shaft, the bearings may be badly worn causing whipping of the shaft.
Clue: One or more rings missing from set. Possible trouble: Bottom of stuffing box badly worn, with packing being extruded into system. Consider able difficulty, such as packing getting into the valves, traps or contaminating the fluid handled, may result.
Clue.- Wear on outside diameter of the packing. Possible trouble: Rings rotating with shaft or loose in the box.
Clue: Bulge in the side of one or more rings. Possible trouble: Adjacent rings cut too short causing packing under pressure to be forced into the open space.
Clue: Rings next to gland followers badly deformed with bottom rings in fair condition. Possible trouble: Improper installation of packings and excessive gland pressure used.
Clue: Packings showing tendency to sheet out or ex trude between rod or shaft and the gland follower.
Possible trouble: Excessive pressure or more likely too great a clearance between the rod or shaft and the gland follower.
In preparing skive cut (45 degree bevel j rings, be sure (he first ring is carefully cut and then tested on the shaft. It can then be used as a master for cut-
Clue: Wearing face of rings dried and charred with rest of packing in good condition.
Possible trouble: High temperatures with lack of lubri-
cation.

5. If Catalysis is possible, it is ben Lo secure a recommendation from your J-M representative, giving ail conditions.
8. When Dry Asbestos Pack-ngs were used for oxygen service it was customary to
specify 100% asbestos content because of the possible combustibility of any or ganic material in the packing. However, 95 99% asbestos packings impregnated with approximately 35% Teflon, J-M Style ^2029, is the most popular style for oxygen service today. It can be used at lernpe^tures from minus 300F up to 50CF, the too service recommencation for any packing containing Teflon. If it were neces sary m any instance to use a packing with no organic content whatever it would be necessary to use a Teflon firammt type or a 100% blue asbestos like ^2014 or 7 2019, and the sea'abiliij in the service involved would determine the style.
7. Concentrations of sulphuric acid up to 4Q% may be handled by the Teflon impregnated packings. We have specified the Teflon filament types to take care of ail concentrations.

General Classification of Chemicals ^
This table need be used only when the chemical being handled is not listed in the Selection Chart on the preceding pages.
We have assigned-arbitrary chemical code symbols as shown below, to each general class of chemicals. In the Selection Chart on the preceding pages, these symbols appear at the left of each liquid listed. Thus, each chemical is classified.
In making your Packing selection, should you fail to find a particular liquid on the Selection Chart the use of these symbols, along with the classifications below', will enable you to decide which Packing is
most suitable. For example, if a particular aromatic hydrocarbon is not listed in the chart, you can deter mine by reference to the General Classification of Chemicals below that aromatic hydrocarbons are code "01B". Then, checking the Selection Chart list ings coded "01B" and choosing a hydrocarbon closely related to'the liquid iff question, you can determine if a "T" Packing is required, or if an "S" type or even a "G" Packing will handle the liquid.

jj* All chemicals used in industry cannot be classified into a brief table without
taking liberties. This has been done here in assigning a general class to a medium inasmuch as the sole purpose is to indicate to the engineer which packing will with stand service in specified media without deterioration. Some compounds are such that classification as one type or another is entirely arbitrary. Where this condition is extreme, we have resorted to a classi fication "commercial and miscellaneous''. The symbols for classification of chemicals ("OlA" for example) have no meaning other than identification for the purposes of this table.
