Pamargan flange seals

Specially designed for pipework with flanged joints, the pamargan flange seal (PFS) consists of a stainless-steel frame and a vulcanized elastomer lip. Thanks to its double lip, the PFS ring ensures a permanent seal, eliminates fugitive emissions and reduces downtime during maintenance operations. It is the ideal solution for all bolted flanged joints. The PFS ring is an effective replacement for spiral-wound gaskets.

Main Benefits

Permanent seal provided by a double sealing line, with no fugitive emissions
Reduced assembly and maintenance time
Reusable, durable and resistant to extreme conditions
Uniform compression (independent of tightening torque)
Compression stops and anti-extrusion seal
GRP (Glass-Reinforced Plastic) flanges: installation without a support ring
