The NBR O-Ring (Nitrile Rubber O-Ring) is one of the most widely used sealing components due to its excellent resistance to oils, fuels, and hydraulic fluids. Manufactured from nitrile butadiene rubber (NBR), these O-rings combine durability, affordability, and reliable sealing performance, making them ideal for a wide range of industrial and automotive applications.
Available in standard AS568 sizes as well as custom specifications, NBR O-rings are suitable for both static and dynamic sealing environments. Their excellent balance of mechanical properties and chemical resistance makes them a cost-effective and versatile sealing solution.
