Piston Seals

This two piece piston seal design comes made with a heat-stabilized, thermoplastic step-cut ring along with a profiled NBR energizer. This product offers extreme strength and resistance to extrusion, a very high resistance to abrasion, and ease of installation thanks to the step cut design and chamfered edges. The design also allows the seal to pass over ports without damage and offers greater resistance to surface roughness in comparison to any elastomer seals. The profiled energizer offers improved dynamic sealing ability, responding quickly to pressure changes and providing excellent sealing characteristics under a wide range of pressure conditions.

Glass Filled Nylon Material | 2.942 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 | 2.85 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Style PSA-58 piston seals combine a heavy duty, fabric reinforced seal with two polyacetal “L” bearings. This construction allows the seal to withstand pressures up to 5,000 PSI. “L” bearings also react to pressure to prevent extrusion and support the piston. For 2-piece pistons.
