PSC

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.

HerculesÆ Sealing Products also offers a wide base (WB) Style PSC piston seal. These wide base seals have the same characteristics of the standard PCS seals but offer a wider base, eliminating the need to use back-up rings to accommodate wider grooves.
NOTE: Piston diameter dimensions are given for piston without wear rings.

Product numbers ending in 'F' are made from a Fluorotrel Compound, which is a tough, wear-resistant material able to run at temperatures up to 275° F. Fluorotrel is also resistant to fluids that are incompatible with polyurethane such as water, glycol, water in oil, mineral oil and petroleum. Consult our Engineering Department for other fluids compatible with Fluorotrel.
NOTE: Piston diameter dimensions are given for pistons without wear rings.
