O-Rings - HNBR, Black, 90 Shore A
O-rings are circular sealing rings with a round cross-section. When fitted into a groove and compressed between two surfaces, the ring forms a seal that prevents the escape of liquids or gases. O-rings are suitable for both static and dynamic applications.
These O-rings are made from HNBR (hydrogenated nitrile butadiene rubber), produced by the hydrogenation of nitrile rubber. This process gives HNBR higher heat resistance and better resistance to ozone and ageing than standard NBR, while keeping its resistance to oils and fuels. HNBR also has high mechanical strength and abrasion resistance, and at 90 Shore A it offers good resistance to extrusion in high-pressure applications.
Chemical Compatibility
Limitations
Not recommended for use with aromatic hydrocarbons, chlorinated hydrocarbons, ketones (such as acetone), esters, ethers, strong acids, glycol-based brake fluids or fuels with a high aromatic content.
Applications
High-pressure and high-temperature hydraulic systems, oil and gas equipment, automotive fuel systems and general industrial machinery.
Installation Guidance
Make sure the groove and mating surfaces are clean and free from burrs, and that the surfaces have a good finish, as a 90 Shore A compound is less able to seal against rough surfaces. Because of its hardness, more force is needed to fit the ring. Apply a thin film of compatible lubricant before fitting, and do not stretch or roll the O-ring over sharp edges or threads.
