PTFE Sanitary Tri-Clamp® Gaskets are the material of choice where low temperature flexibility and hygienic seal memory are not required. We don't recommend using PTFE Sanitary Gaskets where large temperature variations frequently occur because the affect on the PTFE's density makes joints more prone to leakage. With that said we recommend using high pressure clamps to help negate the affects of any temperature fluctuations. PTFE gaskets provide excellent heat resistance, second only to Tuf-Steel®, with an operating range from -100°F to 500°F. From a chemical standpoint PTFE has good stability, almost no extractables, a low absorption rate, and excellent resistance to process fluids. These Tri-Clamp® Gaskets can remain in service for long periods of time in both water and steam applications. If a slight misalignment of the joint is observed it is recommended to instead use Rubber Fab's Tuf-Flex® Gaskets consisting of a PTFE contact surface grafted to an EPDM core.
