These 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 to standard 70A nitrile. Their increased durability makes them ideal for demanding applications. Not recommended for use with phosphate ester fluids. Bulk discounts available for large quantity purchases.
