HPSI

Made from 70A hydrogenated nitrile butadiene rubber (HNBR), also known as highly saturated nitrile, these O-rings provide superior resistance to heat, oil, fuel, and ozone compared to standard 70A nitrile O-rings. With enhanced mechanical strength and abrasion resistance, they offer increased durability, especially in high-performance applications. These O-rings meet SAE standard AS568 inch sizing and are not recommended for use with phosphate ester fluids. Bulk discounts are available for large quantity purchases.
