Engineered for demanding hydraulic applications, this U-seal delivers reliable dynamic sealing performance in cylinders, actuators, and rams. Manufactured from 95A Shore A durometer polyurethane, it offers superior abrasion resistance, high extrusion resistance, and excellent pressure retention — outperforming standard rubber seals in high-cycle environments.
Key Features
Material: Polyurethane (PU), 95A Shore A durometer
Seal Profile: U-cup / U-seal for single-acting or double-acting piston and rod applications
Pressure Rating: Suitable for high-pressure hydraulic systems
Temperature Range: -40°F to +212°F (-40°C to +100°C)
Abrasion Resistance: Exceptional — ideal for dirty or contaminated fluid environments
Extrusion Resistance: High durometer formulation minimizes seal extrusion under pressure spikes
Fluid Compatibility: Compatible with petroleum-based hydraulic oils, water-glycol fluids, and most mineral oils
Typical Applications
Hydraulic cylinders (piston and rod sealing)
Linear actuators and rams
Mobile hydraulics and heavy equipment
Industrial presses and machine tools
