Sanitary Tri-Clamp® Perforated Plate Gaskets - Tuf-Steel®
Tri-Clamp® Tuf-Steel® Perforated Plate Gaskets are manufactured with a 22 Gauge 316L Stainless Steel Perforated Plate that has been flow trapped into the gasket body. These perforated hole gaskets are available standard with 0.033", 0.045", 0.062" (1/16"), 0.094" (3/32"), 0.125" (1/8"), 0.187" (3/16") and 0.250" (1/4") perforations in varying center types, please see the reference chart below for exact specifications. The center type is the center to center distance between each perforation and correlates to the holes per square inch and open area % of each gasket.
With a stringent ASME-BPE design, these filtration gaskets can be utilized for particulate removal in a number or processes and industries. Whether being used as a pre-filter for expensive membrane filters, or straining particulate in fill and finish products, these sanitary gaskets can save you from equipment wear and product contamination.
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 Torque-Rite® Clamp 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.
