O-Rings

NBR O-Ring

NBR (Nitrile Butadiene Rubber) O-rings are the most widely used sealing elements in industrial applications. Manufactured from high-quality nitrile rubber in a Class 100,000 cleanroom, they offer excellent resistance to oils, fuels, and hydraulic fluids. Suitable for static and dynamic sealing in hydraulic systems, pneumatic equipment, automotive engines, and water treatment facilities. Available in standard AS568 sizes as well as custom non-standard dimensions.
