Polyurethane 95A Durometer Hydraulic U-Seal

Polyurethane 95A Durometer Hydraulic U-Seal

Engineered for demanding hydraulic applications, this U-seal delivers exceptional sealing performance in dynamic rod and piston environments. Manufactured from premium 95A Shore A durometer polyurethane, it provides the ideal balance of flexibility and wear resistance required for high-cycle hydraulic systems.

Key Features

• Material: Polyurethane (PU), 95A Shore A durometer
• Seal Type: U-seal (lip seal) — single-acting dynamic seal
• Application: Hydraulic cylinders — rod and piston sealing
• Operating Pressure: Up to 5,000 PSI (345 bar) depending on size and configuration
• Temperature Range: -40°F to +212°F (-40°C to +100°C)
• Fluid Compatibility: Mineral-based hydraulic oils, water-glycol fluids, and most synthetic hydraulic fluids
• Low friction profile minimizes stick-slip and extends cylinder service life
• Self-energizing lip design ensures positive sealing under both static and dynamic conditions

Typical Applications

• Hydraulic cylinders (mobile and industrial)
• Linear actuators
• Heavy equipment and construction machinery
• Agricultural and forestry equipment
• Material handling systems
