Tuf-Steel Gasket

The original Tuf-Steel gasket, a Rubber Fab product innovation, is the strongest gasket in the pharmaceutical, biotech, food and beverage industries. Whatever your application, there’s a gasket in the Tuf-Steel family ready to do the job.

Tuf-Steel is ideal for extreme temperature applications, such as steam, hot oil and friers, where temperatures range from -350°F to 550°F. Unlike traditional solid PTFE and PTFE envelope style gaskets, Tuf-Steel does not revert, eliminating creep and cold flow, resulting in a leak-free seal. Because the superior strength and chemical resistance of Tuf-Steel allows it to go the distance without leaking, it significantly reduces maintenance and system downtime by staying in place when cleaning and validating a system.

Testing and a decade of documented application usage have demonstrated that Tuf-Steel is the choice for perfect surface performance, outstanding durability and extended service life in both SIP (steam in place) and WFI (water for injection) applications.
