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
