High-Performance Composite Sealing for Demanding Hydraulic Cylinders
This urethane composite piston seal assembly combines the abrasion resistance and pressure-handling capability of polyurethane with the low-friction characteristics of a composite construction — delivering superior sealing performance in high-cycle, high-pressure hydraulic cylinder applications. Engineered to AS568 dimensional standards, this assembly is a direct-fit solution for OEM builds and MRO replacement across a broad range of bore sizes.
Key Benefits
Urethane construction provides exceptional abrasion and extrusion resistance
Composite design reduces breakout friction and stick-slip in dynamic applications
Bi-directional sealing for double-acting cylinder configurations
Maintains seal integrity under pressure spikes and thermal cycling
Compatible with petroleum-based and water-glycol hydraulic fluids
Drop-in replacement for standard hydraulic cylinder bores
Typical Applications
Heavy-duty industrial hydraulic cylinders
Mobile and construction equipment hydraulics
High-cycle actuator and press assemblies
OEM and MRO hydraulic system maintenance
