There is no beating the Tuf-Steel family in SIP, WFI and hot oil applications because Tuf-Steel® maintains seal integrity in applications with large temperature variations. With a 500 steam cycle guarantee, this metal detectable gasket will easily out perform any elastomeric or perfluoroelastomer gasket and will remain in service for extended periods of time. It is the material of choice when chemical and heat resistance are required. Minimum creep and cold flow, non-stick, ultra-low absorption, no pigmentation and it will not revert. This gasket is tough!
