NBR O-rings are made from nitrile rubber, which is a synthetic polymer derived from the copolymerization of acrylonitrile and butadiene. The acrylonitrile (ACN) content might vary from 18% to 50% and determines the physical properties of the o-ring. If the ACN is high, the component will have high resistance to oil and fuel, but low compression resistance and temperature flexibility.

Common Names

NBR, Buna-N, Nitrile
