Hydraulic O-Rings

Hydraulic O-rings are critical sealing components used to prevent fluid leakage in high-pressure hydraulic systems. We supply reliable hydraulic O-rings designed to perform under demanding pressure, temperature, and fluid conditions.

O-Rings for Hydraulic Systems

Our hydraulic O-rings are manufactured with precise tolerances to ensure effective sealing in static and dynamic hydraulic applications. They are suitable for pumps, valves, cylinders, and hydraulic fittings.

Recommended Materials for Hydraulic O-Rings

• NBR (Buna-N): excellent oil resistance and cost-effective
• HNBR: enhanced temperature and pressure resistance
• FKM (Viton®): high temperature and chemical resistance
• EPDM: suitable for water-based hydraulic fluids
