Buna-N 90 O-Rings
When pressure spikes, soft rings extrude and leak. Step up to Buna-N 90 O-rings for tougher, high-pressure sealing with solid resistance to oils, solvents and shop fluids. Yellow stripe ID helps you grab the right ring fast. Choose 1/16", 3/32", 1/8" or 3/16" wall, plus straight-thread rings that meet ASA, ASME, SAE and MS.
