TUF-FLEX
The Finest Gasket in the World

TUF-FLEX

Introducing a Technologically Advanced New Gasket
TUP-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 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 gasket.

Performance With Exceptional Purity
Because its elastomer core is protected by a unitized layer of PTFE, TUF-FLEX gaskets will not release elastomer extractables or particulates totally eliminating spalling. The result is an excep¬tionally maintained sanitary tubing ID with no ID invasiveness or system contamination.

Performance Superior to Elastomers
An elastomer gasket under SIP temperatures or chemical contact can revert. The soft, gummy consistency will invade into the sanitary ID, shear and cause product contamination. At the same time, the reverting elastomer will stick to the ferrule's face increasing clean-up costs and down time. Because all elastomers are metamorphic, over time, they continually undergo deterioration resulting in the release of extractables and TOCs. 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 gaskets.

Performance Without the Problems of PTFE
Solid PTFE expands five times more per inch, per °F compared with the connected stainless & steel ferrules causing creep — into the ID and outside the OD. When PTFE returns to room temperature. the PTFE gasket shrinks in equal measure leaving unacceptable gaps in the system which results in leaks. With its inner elastomer core and PTFE layer, TUF-FLEX eliminates the shrinkage, gaps and leaks associated with PTFE gaskets.

Performance More Reliable than PTFE Envelope Gaskets
Because the envelope gasket is not unitized, the inside elastomer and the outside PTFE act independently of each other, In T processes, this construction results in gaps and shrinkage. TUF-FLEX Is totally unitized allowing no gaps thereby delivering more reliable performance.

Performance of Up to 100 Steam Cycles - Guaranteed!
TUF-FLEX provides long serv¬ice life. TUF FLEX eliminates clean-ups and service inter¬ruptions. And when used and maintained properly, TUF-FLEX performs through up to 100 steam cycles guaranteed!   With TUF-FLEX. the Proof is in the Performance.
