HNBR

HNBR O-rings are made from hydrogenated nitrile rubber, offering superior resistance to heat, ozone, and a wide range of chemicals, including oils and fuels. HNBR combines the durability of nitrile rubber with the enhanced thermal stability and environmental resistance of hydrogenation. These O-rings are commonly used in automotive, aerospace, and industrial applications, especially where performance under extreme conditions is required.

HNBR Recommended Uses

• Automotive sealing applications
• Oil and gas industry
