HNBR o-rings are manufactured from hydrogenated nitrile specially engineered for superior temperature and chemical resistance compared to traditional NBR materials. HBNR o-rings also feature superior abrasion, wear, and compression set resistance, making them an excellent choice for a wide range of critical applications. Hydrogenated Nitrile was specifically developed for increased temperature resistance and better compatibility with new automotive fuels. In addition, hydrogenated nitrile offers better strength with minimal degradation at higher temperatures. Exact specifications and chemical resistances vary by compound formulation.
