Rubber Fab – TUF-flex – Tri-Clamp gasket

Suited for SIP/CIP conditions

RX Code: WFK / WFL

Tuf-Flex® Tri-Clamp® Gaskets by Rubber Fab are unique unitized seals, revolutionizing purity, performance, and flexibility standards. Specifically engineered for critical applications in pharmaceuticals, biotechnology, ultra-pure water, WFI, and challenging food and beverage processing, Tuf-Flex® surpasses other hygienic seals, reducing costly process interruptions. Its design integrates a PTFE layer with an EPDM rubber core, ensuring exceptional purity and flexibility. This bonded construction prevents product contamination, service interruptions, and cleaning costs associated with traditional elastomer seals. With Tuf-Flex®, elastomer extractables and particulates are eliminated, maintaining sanitary tubing integrity without invasiveness or system contamination. Moreover, the PTFE-grafted elastomer maintains its integrity without requiring re-torquing or leaking.


  • No re-torquing necessary
  • Flexibility of an elastomer with the chemical resistance of PTFE
  • Non-stick surfaces
  • Up to 100 SIP cycles guaranteed


  • Size ½” up to 8″
  • Temp From -28C to + 200 C
  • Imperial, DIN and ISO size
