INERTEX "LTC" and "LTC-NR" Low Torque Gaskets AN INDUSTRY-DESIGNED ANSWER To an Every Day Industry Problem Every Day Real Industry Problems! The Industry and Inertech Solution Design a gasket that seals at torques below piping mfgs. FRP piping mfgs'. recommended maximum torque is too low for a leak-free joint. recommended levels. Gasket materials are too hard and/or do not seal at recommended torque levels. Use a soft compressible material that seals at low loads. When leakage is detected, mechanics frequently torque bolts to stop leakageProvide a leak free gasket in the initial installation that maintains its resulting in broken or cracked flanges. leak free performance for the life of the joint. Field personnel often use the wrong gasket material for the media to be sealed. Provide a gasket with total chemical compatibility. Provide a gasket that eliminates broken flanges and resulting Downtime from replacing flanges is very costly. downtime. Provide a long life, leak-free gasket designed to seal within piping Lost product as a result of flange leakage or breakage is extremely costly. manufacturers' recommendations. When higher temperatures are present, mechanics frequently have to re-torque Provide a material that has little to no creep relaxation or cold flow. gaskets to keep them from leaking. INERTEX "LTC" and "LTC-NR" Low Torque Gaskets Co-developed by engineers at Virginia Sealing Products, Inc. and Inertech, Inc., the INERTEX "LTC" and "LTC-NR" Low Torque Gasket designs eliminate the problems most users of FRP, Plastic, or similar fragile piping materials experience every day. No other gasket design does all this! These designs are the only pure PTFE (Teflon ) gaskets designed for FRP flanges! Review the table below and decide for yourself.
