55D; 70A Durometer | Polyester Material | 59.5 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
The MPSU300 is a compact, double-acting piston seal consisting of two parts: a urethane sealing ring with a pronounced sealing edge and a rectangular nitrile energizer to prevent the seal from twisting within the groove. It also has low friction and smooth operating movement even at low linear velocities.

These specifically sized seals are for certain OEM cylinders (primarily Heil & Timberjack). Their use is intended for existing housings where the old seals are dimensionally comparable to the table below. Please call your sales representative if you need additional assistance.
Glass Filled PTFE Material | 1.323 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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.
55D Durometer | Glass/PTFE Filled Polyurethane Material | 4.504 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 | 3 1/2 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.
Fabric Reinforced Nitrile Material | 2 3/4 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
