Unflanged Sanitary Tri-Clamp® Gaskets - Tuf-Steel®

(0)No Reviews yet

Rubber Fab's Tuf-Steel® Sanitary Tri-Clamp® Gaskets are the material of choice when purity, long service life, performance, chemical resistance, and heat resistance are required. Tuf-Steel® Gaskets are 100% leak free when torqued correctly, and will experience minimum creep and cold flow. The Tuf-Steel® material is a unique proprietary blend of non-pigmented PTFE (Teflon®) and 316L Stainless Steel that has been water atomized and passivated. The end result is a Tuf-Steel® Gasket that is non-stick, features no pigmentation, and has ultra-low absorption rates. These Tri-Clamp® Gaskets can maintain seal integrity under large temperature fluctuations with a serviceable temperature range from -350°F to 550°F. We recommend the use of the to get the most out of these gaskets.

Tuf-Steel® is the original metal detectable gasket, the material has always been detectable with metal detectors and magnetic separators. Over 10 years of testing and documented application usage show that Tuf-Steel® is the choice for perfect surface performance, outstanding durability, extended service life and increased up-time for both SIP (steam in place) and WFI (water for injection) applications. Tuf-Steel® Gaskets are ideal for sanitary steam and extreme temperature processes, especially fryer and hot oil applications. Unlike envelope gaskets, the superior strength of the Tuf-Steel® blend will not revert, eliminating creep and cold flow, providing a leak-free seal.
