90A Nitrile Boss O-Rings are made from a harder durometer Buna-N (nitrile) than standard 70A Boss O-rings and are designed specifically for SAE straight-thread O-ring Boss (ORB) fittings in high-pressure hydraulic systems. Engineered for axial compression sealing, these O-rings provide reliable sealing in threaded connections to help prevent leaks. The harder 90A nitrile construction makes them suitable for more demanding sealing applications. Not recommended for long-term use with brake fluids. These O-rings are available in 20 non-standard sizes, with bulk discounts available for large quantity purchases.
