Piston Seals

9.500 X 8.637 X 0.379 Piston Seal

2.000 X 1.606 X 0.129 Piston Seal

This seal, molded from high grade 55D polyurethane, may retrofit the PS1800 seals, considering all dimensions are comparable. This seal material, with a high degree of memory, stretches over the piston and snaps in the groove for immediate assembly. These seals also feature low friction and high abrasion and extrusion resistance which helps to eliminate assembly damage. Piston diameter “I” dimensions are given for pistons without wear rings.

PS3, 7.000 X 6.240 X 0.375 Piston Seal

2.750 X 2.212 X 0.282 Step Cut PS

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 | 3.942 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.
