Expanded PTFE Gasket resistant to all corrosive media. Soft,twistable and bendable, used continue their service and keep its best performance. Excellent anti-wriggle variation ability and cold current resistance. Even in case of cross change of temperature and pressure, good sealing can be assured
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
