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.
95A; 70A Durometer | Polyurethane Material | 2 5/8 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Quad® Rings provide improved stability and lubricity over conventional o-rings, reducing the tendency to spiral in the groove. They interchange standard o-rings in a variety of static and dynamic sealing applications including rotary, reciprocating or oscillating motion.

Style ST-XL wipers are molded from premium urethane and are direct replacements for Style “ST” or “D” wipers. The outside diameter of the ring has a crush lip providing extra interference in the groove. A bead on the shoulder stops contaminates from entering through the groove. The inside diameter is ribbed to prevent pressure traps between the wiper and rod seal.
