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 has 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. Contact Rubber Fab’s Technical Sales Department at 973-579-2959 or sales@rubberfab.com for more information and a free Tuf-Steel® sample.
