VSP# 8381
VSP PITA® OPRA™

100% expanded PTFE gasket with fully encapsulated corrugated, stainless steel insert. Patented construction transforms conventional ePTFE into a “spring energized” PTFE gasket that maintains high tightness throughout thermal cycling in all chemical services.

One piece reduced area gaskets for all lightly loaded flanges:
FRP, PVC, PVDF, Cast Iron & API manways.
Features
Complete encapsulation of the 316SS insert allows the PITA® gasket to retain the chemical inertness of ePTFE.
