Tuf-Flex Gasket

Tuf-Flex Gasket

Introducing a Technologically Advanced New Gasket

TUF-FLEX, the revolutionary new gasket is the world's only unitized gasket, 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 gaskets while eliminating costly process interruptions.

Performance Based on a Revolutionary Composition
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.

Performance With Exceptional Purity
Tuf-Flex Gasket
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.
