' "XVV.- f;'- 'AZ # POWER AUGUST 1960 Specifying the right material for metal packings can make a big difference in seal effectiveness and packing life* Garlock offers a wide choice, each designed for specific temperatures and pressures: GRAPHITIC CAST IRON. Unequaled wearresistant qualities. Graphite assures continuous lubrication between pack ing and rod. Recommended against 1500 p.s.i. pressures, 800F tempera tures. STANDARD HI-LEAD BRONZE. Chosen after years of research, this standard bronze has a yield point of 26,000 lbs./sq. in., a tensile strength of 31,250 Ibs./sq. in. Can be used against 10,000 p.s.i. pressures, 800CF temperatures. HJ-LEAD SUPER BRONZE. Possesses a yield point of 14,750 lbs./sq. in., a ten sile strength of 25,500 lbs./sq. in. Due to better wear properties, it can be used at pressures to 40,000 p.s.i., temperatures to 800F. AMBERITE--PLAIN OR GRAPHITIZED. Tough, strong, high impact strength. Excellent where corrosion and mildly difficult lubricant and wear conditions exist. Apply against 600 p.s.i. pressures, 25CTF temperatures. Other grades available to meet various conditions. BABBITT. Used on soft rods and where corrosion is present, lubrication is lim ited. Standard Babbitt has tensile strength of 10,000 lbs./sq. in. More ex pensive type has better wear qualities. Recommended for 5000 p.s.i. pressures, 425F temperatures. CARBON. Used where no lubricant is allowed. Generally affords the best wear-strength combination available. 700F is recommended temperature limit; pressures may vary according to grade of carbon used. TEFLON.* Far superior to many other rod packing materials because of out standing chemical resistance, ability to retard wear and friction. Available in carbon- or glass-filled.
