Tuf-Flex®
PTFE grafted to an EPDM rubber inner core

Tuf-Flex®, the revolutionary sanitary gasket is the only unitized seal setting new standards for purity, performance and flexibility. Designed to meet critical requirements in pharmaceutical and biotechnology, Tuf-Flex® outperforms other sanitary hygienic seals and increases uptime by helping eliminate costly process interruptions. A Tuf-Flex® sanitary gasket’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. Tuf-Flex® will behave like an elastomer but will prevent product contamination, service interruptions and clean-up costs associated with traditional elastomer seals. Because there’s no cross flavor contamination, Tuf-Flex® increases processing uptime by minimizing need for changeout.
