Made from harder durometer nitrile than the standard 70A Boss series rings, these O-rings 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 prevent leaks in threaded connections. Not recommended for long term use with brake fluids, these O-rings are available in 20 non-standard sizes, with bulk discounts for large quantity purchases.
