Hydraulic Cylinder Oil Seal Ring

Key features

• Precision-molded polyurethane (PU) with Shore A 90±2 hardness delivers outstanding wear resistance and dimensional stability for demanding hydraulic applications.
• Balanced inner and outer lip devise provides flexible, tight sealing under pressures up to 40 Mpa, effectively preventing oil leakage and extending equipment service life.
• Engineered for easy installation with impact resistance and tolerance for large extrusion gaps, reducing downtime during maintenance or replacement.
• Versatile fit for hydraulic cylinders, guide rods, piston rods, hoists, pumps, and static-pressure one-way piston seals in automotive, machinery, marine, and industrial systems.
• Operates reliably in temperatures from -20°C to +100°C, making it suitable for both indoor workshops and outdoor environments.
