Product Description

Expanded PTFE Gasket

Style 1310 White Expanded PTFE Gasket Expanded PTFE Gasket is cut from Expanded PTFE gasket sheet, our expanded PTFE gasket sheet made with only pure PTFE resins. It is suitable for use in steel flanges as well as flanges where a highly compressible gasket is required. Expanded PTFE Gasket is also suitable for sealing flanges with irregular surfaces. It will not exhibit the cold flow problems associated with virgin PTFE or the hardness problems of some other filled PTFE products. It has excellent sealability, cuts easily, and separates cleanly from flanges after use
