Two such Joint# ara now being Barketed. n-fTM" jcrvT Tha first of thaaa, a naoprana gasket for uaa in conventional ball and spigot plpa, la being earketed under tha trade nan* "Ty-Seal" by tha tyler Plpa and Foundry Co., Tyler, Tax. Baeauaa of tha coepatltiva threat of thla typa of Joint, Lead Induatrlaa Aasoclation haa daaaad it advlaabla to conduct a tlneooat study of thla Joint vereue tha lead-calked Joint, A copy of thla etudy la attached. 0-h u b* j o in t Tha aacond developnmt In thla area la newer and embrace a an entirely now concept in Jointing ciet-iron toll pipe, that la, no hub la required. Thla Joint, trade-naaed "No-Hub" haa been developed through tha afforta of tha Caat Iron Soil Pipe Inatituta, and la being actively promoted by at laaat two caatlron plpa aanufecturora. Thla Joint la Bade by lnaarting tha two lengtha of plpa to be Joined into a neoprene ring which la than drawn tight by Beena of a atainleea ateal ring incorporating two hoae typo clasping ring*. As far at we can determine, tha "No-Hub" typa of joint la not yet ecnMrcixlly available but is being offered to city and state pliabing tasting facilities in aa attempt to get then approved for uaa. As soon aa tha Aasoclation can obtain tha "No-Hub" typa joints, wa plan to conduct a stellar tiae-eoat study that conducted with tha "Tjr-Seal" type Joint, aa attached. Additional eopiaa of this report are available upon request. Sincerely yours, David X. Borein* ^ Secretary A LI A184 5 3 LEAD INDUSTRIES ASSOCIATION. INC. MtW VOS* I.

Keating st the Voorhee# Technical Institute, 3C4-326 East 67th Strest, K-ew fork 21, B.T. whsrs hs m ths Bead of ths Apprentice Training Progran. Ths roughlng-in ni prepared In accordanoe with ths Kev Tork City cods and la alKLiAr to what would bo standard practice In nany arsas of ths country, that la, cast-iron pips for ths stack and houas drain, galvanised or black Iron for wasto arms and a load band. A photograph of ths aassabliss arsctsd for ths tost la attachsd, Ths rssulta of ths study lndlcats ths lsad-oakta roughlng-ln to bs just irxler 6 par esnt chsapsr than ths nsoprsna (Ty-Ssal) installation. Si.-mary cost figures ars given In Tabla X with more dstailsd data In Tablsa 11 and III. All aatsriala wars purchaasd through a local supply houas and no freight charges ars lncludsd. Tool costa ars not lncludsd and It could bs argusd that a coatplata nsoprtna (Ty-Seal) job, using nothing but ths required typs of cast-iron pips and fittings, will require lata investment In toola,and this la trus. In this tvsni, Lewevsr, material costa of every job would bs substantially hlghar. It should also bs polntsd out that If a slngls length of atssl pips or a laad band la incorporated la a nsoprsna (Ty-Seal) job, than practically all of ths tools required for a com plete lsad-oaktn job would bs nscsstary. It la also Important to note that ths cast-iron pips required for ths neoprene (Ty-Setl) joint la aada to closer tolerances than conventional cast-iron pips and without a bssd on ths spigot end. Because of the close tolerances required whenever a piping netsrial other than ths special cast-iron ia used for a connection, a leadcalked joint la necessary. As far as ia currently known, ths cast-iron pips required for use with ths neoprene (Ty-Seal) joint la nada only by ths Tyler Pips and Foundry Co., Tyler, Tex. One other decided advantage of ths lsad-oakua joint is that It can bs used with any typs of bell end spigot cast-iron pips.
