Engineered for demanding hydraulic applications, this Polyurethane U-Seal delivers exceptional sealing performance where standard elastomers fall short. At 95A Shore durometer, it strikes the ideal balance between flexibility and load-bearing rigidity — resisting extrusion under high-pressure cycling while maintaining a reliable dynamic seal on piston and rod surfaces.
Key Benefits
High Durometer (95A): Superior extrusion resistance in high-pressure hydraulic systems
Polyurethane Construction: Outstanding abrasion resistance and mechanical strength compared to Buna-N or PTFE alternatives
Wide Temperature Range: Performs reliably from -40°F to +200°F (-40°C to +93°C)
Chemical Resistance: Compatible with petroleum-based hydraulic fluids, mineral oils, and water-glycol fluids
Low Compression Set: Maintains sealing force over extended service life
Typical Applications
Hydraulic cylinders (piston and rod sealing)
Linear actuators
Heavy equipment and mobile hydraulics
Industrial presses and injection molding equipment
Agricultural and construction machinery
