Engineered for demanding hydraulic cylinder applications, this urethane rod buffer seal acts as a pressure-relief pre-seal, protecting the primary rod seal from pressure spikes and fluid contamination. Its high-performance polyurethane construction delivers exceptional abrasion resistance, tear strength, and resilience across a wide operating range — making it the preferred choice for mobile equipment, industrial hydraulics, and heavy-duty cylinder rebuilds.
Key Benefits
Absorbs pressure peaks before they reach the primary seal, extending overall seal system life
Superior abrasion and extrusion resistance compared to standard rubber seals
Low friction profile reduces stick-slip and rod wear
Excellent chemical resistance to petroleum-based hydraulic fluids
Maintains dimensional stability across temperature and pressure cycles
Typical Applications
Hydraulic cylinders in mobile and industrial equipment
Construction, agricultural, and material handling machinery
Pneumatic and hydraulic rod and piston assemblies
Material
Polyurethane (Urethane) — 90–95 Shore A hardness typical. Consult product specifications for exact durometer, temperature range, and fluid compatibility.
