Tuf-Flex® Tri-Clamp® Gaskets from Rubber Fab Technologies Group are the world's only unitized seal, setting new standards for purity, performance and flexibility. Designed to meet critical requirements in pharmaceutical, biotechnology, ultra-pure water, WFI (water-for-injection) and difficult food and beverage processing, Tuf-Flex® outperforms other hygienic seals while eliminating costly process interruptions.

A Tuf-Flex® hygienic seal's contact surface is a layer of PTFE grafted to an EPDM rubber inner core. This totally bonded construction provides an exceptionally pure and incredibly flexible seal. By grafting the elastomer with a layer of PTFE, Tuf-Flex® will behave like an elastomer but will prevent the product contamination, service interruptions and clean-up costs associated with elastomer seals. Because its elastomer core is protected by a unitized layer of PTFE, Tuf-Flex® hygienic seals will not release elastomer extractables or particulates, totally eliminating spalling. The result is an exceptionally maintained sanitary tubing I.D. with no I.D. invasiveness or system contamination, and the PTFE grafted elastomer in a Tuf-Flex® seal will maintain I.D. without re-torquing or leaking.
