PSC Piston Seal Assemblies

PSC Piston Seal Assemblies

The Style PSC is a double acting piston seal designed to replace o-rings, quad-rings, and T-seals with the same groove dimensions (O-ring dash number). Style 575 urethane back-up rings may be added to either or both sides of the 'PSC' to accommodate wider groove widths. The PSC is made of 95A Durometer polyurethane, giving it high extrusion and abrasion resistance. The crowned sealing surface produces a positive seal from vacuum to high pressure.


NOTE: Piston diameter 'I' dimensions are given for pistons without wear rings.
