Piston diameter “I” dimensions are given for pistons without wear rings.
Glass Filled Nylon Material | 2.408 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Designed to fit on one or two piece pistons, this piston seal employs a nitrile seal for high sealability, nylon split backups for extrusion resistance, and two split bearing rings. No further support bearings are required.
90A Durometer | Nitrile Material | 2 1/4 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Compact and easy to install, the Style PSA-65 piston seal is a simple and economical design for pressures up to 3,000 PSI. The assembly consists of a nitrile rubber seal and two polyacetal bearings to support the piston. For 1-piece pistons.
Nitrile Material | 1 5/8 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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.

These piston seals provide bi-directional, low friction sealing with increased stability and superior leakage control. The square cut energizer provides low pressure sealing and eliminates backside leakage. This seal also effectively seals between different fluids on each side of the piston seal, making gas/liquid sealing combinations possible. Piston diameter “I” dimensions are given for pistons without wear rings.
40% Bronze Filled PTFE Material | 5.66 in Nominal Inner Diameter | Piston Seal

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.
94A Durometer | Urethane Material | 12 in Nominal Inner Diameter
Features
- Crush lip to provide extra interference
- Bead on the shoulder to keep contaminants out
- Ribbed ID to prevent pressure traps
