Engineered for demanding hydraulic cylinder applications, this Polyurethane Hydraulic Piston Seal Assembly delivers superior sealing performance across a wide range of operating pressures and temperatures. Manufactured from high-grade polyurethane (PU), these seals offer exceptional abrasion resistance, high tensile strength, and outstanding resistance to hydraulic fluid degradation — making them the go-to choice for industrial, agricultural, mobile, and heavy-equipment hydraulic systems.
Key Benefits
High Abrasion Resistance — Polyurethane compound withstands continuous piston stroke cycles without premature wear
Excellent Pressure Handling — Maintains a reliable seal under high-pressure hydraulic conditions
Low Friction Profile — Reduces stick-slip and energy loss for smoother cylinder operation
Fluid Compatibility — Compatible with mineral-based hydraulic oils, water-glycol fluids, and most synthetic hydraulic fluids
Wide Temperature Range — Performs reliably from -40°F to +212°F (-40°C to +100°C)
Easy Installation — Precision-molded profile ensures correct seating in standard piston grooves
Available in a full range of dash sizes and cross-section dimensions to fit standard and custom cylinder bores. Contact us for bulk pricing or custom specifications.
