NBR O-Rings

Shop NBR O-rings by inner diameter and cross section in metric and AS568-style sizes. NBR is commonly selected for petroleum oils, grease, compressed air, and general industrial sealing.

NBR is not usually the first choice for ozone, prolonged outdoor weathering, or many strong polar solvents. Confirm the operating fluid, temperature, pressure, and seal motion before ordering.
