8" PTFE, Teflon, Tri clamp, Tri Clover, Sanitary, Gasket SealThese PTFE gaskets, commonly known as Teflon gaskets, are best known for their low friction property. High melting temperature, high corrosion resistance, high resilience and a long product life increases its value as a sealing material. One important property for these gaskets are their lack of memory that results in material creep. This allows them to seal and conform to the mating surface providing a secure seal.
