hydraulic oil o-ring material

The O-rings used in hydraulic systems are usually made of different types of materials, and the specific material selection depends on the working conditions, temperature, pressure, and type of fluid used in the hydraulic system. The following are some common hydraulic oil O-ring materials:

Nitrile rubber (NBR): NBR is a common O-ring material widely used in general hydraulic systems. It has good oil resistance, wear resistance, and elasticity, and is suitable for working temperatures ranging from -30 ° C to+100 ° C.

Viton: Viton is a high-performance fluororubber with excellent high-temperature resistance and chemical corrosion resistance. It is suitable for applications at high temperatures (-15 ° C to+204 ° C) and extreme environments, especially those involving acids, alkalis, solvents, and oils.

Propylene rubber (EPDM): EPDM has excellent weather resistance, aging resistance, and UV resistance, suitable for outdoor applications and exposure to UV conditions. Its operating temperature range is usually between -40 ° C and+150 ° C.

Silicone: Silicone rubber has excellent high-temperature resistance and chemical corrosion resistance, suitable for high-temperature (-55 ° C to+230 ° C) and food grade applications.

Polyurethane: Polyurethane O-rings have excellent wear resistance and are suitable for applications with high impact, high pressure, and high dynamic loads. Its operating temperature range is usually between -40 ° C and+100 ° C.

Tetrafluoroethylene (PTFE): PTFE is a very low friction material suitable for applications under high temperature and pressure conditions. Its operating temperature range is usually between -200 ° C and+260 ° C.

Fluorosilicone: Fluorosilicone rubber combines the properties of silicone rubber and fluororubber, suitable for applications with high temperature (-60 ° C to+225 ° C) and high chemical corrosion requirements.

When selecting hydraulic oil O-ring materials, it is necessary to consider the specific working conditions, fluid type, temperature range, and chemical properties of the hydraulic system. Different materials have different advantages and limitations, so choosing the appropriate material is crucial for system performance and sealing performance. We suggest consulting with material suppliers or manufacturers based on your specific application and needs to ensure the correct selection of materials.
