Introduction to HNBR O Ring
HNBR (Hydrogenated Nitrile Butadiene Rubber) O – rings are high – performance sealing components. They are derived from nitrile rubber through a hydrogenation process, which endows them with excellent resistance to heat, oil, ozone, and chemicals. HNBR O – rings can operate in a wide temperature range, typically from – 40°C to 150°C, and in some special cases, up to 175°C. They are widely used in various industries such as automotive, aerospace, oil and gas, and mechanical engineering, where reliable sealing is crucial. HNBR O Ring
