Chemline GA Series Low Torque Gaskets are recommended for all plastic piping systems to prevent initial flange leakage due to bolt over tightening. They are especially recommended for all Chemline solid plastic flanged body valves. The unique double convex ring design provides optimum sealing with a fraction of the bolt torque required for flat face gaskets. The Teflon®
PTFE and PVDF gaskets have 0.4 mm sheet material bonded to EPDM. This increases elasticity, lowering bolt torques required to seal.
