PA-90URE-2.5x0.255 - PSC-330 | CRC Distribution Inc.

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