O-ring 325x5,3 NBR 70 ShA

Construction and NBR material properties

O-ring 325x5,3 NBR 70 ShA is an industrial sealing ring designed for hydraulic, pneumatic and mechanical systems requiring reliable and durable sealing performance. The large 325 mm inner diameter and 5,3 mm cross section make this sealing solution suitable for heavy duty industrial assemblies and pressure operated systems.

NBR material, also known as nitrile rubber, provides excellent resistance to mineral oils, greases, hydraulic fluids and standard industrial operating environments. The 70 Shore A hardness ensures an optimal balance between flexibility, sealing efficiency and mechanical durability in both static and dynamic applications.
