70A HNBR Boss O-Rings are designed for SAE straight-thread O-ring Boss (ORB) fittings in hydraulic systems. Made from 70A hydrogenated nitrile butadiene rubber (HNBR), also known as highly saturated nitrile, they provide enhanced resistance to heat, oil, fuel, and ozone compared with standard 70A nitrile. Their increased durability makes them well suited for demanding hydraulic applications. Not recommended for use with phosphate ester fluids. Bulk discounts are available for large quantity purchases.
