70A HNBR O-Rings are made from hydrogenated nitrile butadiene rubber (HNBR), also known as highly saturated nitrile, and provide enhanced resistance to heat, oil, fuel, and ozone compared with standard 70A nitrile O-rings. Their improved mechanical strength and abrasion resistance provide increased durability for demanding and high-performance applications. These O-rings conform to SAE AS568 inch sizing and are not recommended for use with phosphate ester fluids. Bulk discounts are available for large quantity purchases.
