- A Solid PTFE Type 1 Gasket is guaranteed to fail in SIP Conditions. They will creep, cold flow and leak at ΔT.
- Performance without the Problems of PTFE
Solid PTFE expands five times more per inch, per ºF compared with the connected stainless steel ferrules causing creep into the LD. and outside the O.I When PTFF 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.

- The envelope Gasket construction provides inconsistent results between the two materials. It will also creep, cold flow and leak over time.
- 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 ΔT processes, this construction results in gaps and shrinkage. TUF FLEX is totally unitized allowing no gaps thereby delivering more reliable performance.

- The PTFE grafted elastomer in a TUF-FLEX gasket will maintain I.D. without re-torquing or leaking.
- Performance of Up to 100 Steam Cycles – Guaranteed!
TUF-FLEX provides long service life. TUF-FLEX eliminates clean-ups and service interruptions. And when used and maintained properly, TUF-FLEX performs through up to 100 steam cycles guaranteed!
