Flange Sealant
Polymeric Flange Sealants - PFS
PFS replaces most conventional gaskets on metal surfaces. It cures in the absence of air and will not shrink, tear or crack and provides maximum face to face contact of mated parts. PFS Gasket provides an instant seal at low pressures and fully cures in 1 to 8 hours depending upon part configuration and clearance. No retorquing of flange bolts is required as stress relaxation of this Polymeric Flange Sealant does not occur and face to face contact of the metal surfaces makes this unnecessary.
