TUF-FLEX® SEAL COMPARISON
 
TYPE I
A Solid PTFE
Type I Seal is guaranteed to fail in SIP conditions. They will creep, cold flow and leak at T.
TYPE III
ENVELOPE
The Envelope Seal construction provides inconsistent results between the two materials. It will also creep, cold flow and leak over time.
TUF-FLEX®
The PTFE grafted elastomer in a TUF-FLEX hygienic
seal will maintain I.D. without re-torquing or leaking.
