Nitrile O Ring Manufacturers

A nitrile O ring is an O-ring seal manufactured from the synthetic elastomer nitrile, which is also known as Buna-N. Nitrile is a synthetic rubber copolymer with high resistance to hydrocarbon fuels and petroleum-based oils. This property, combined with its operating temperature range from -65°F to +275°F, has made it one of the most commonly used elastomers in the production of O-rings. Nitrile rubber is also superior to most other elastomers due to its good resistance to compression set, as well as tearing and abrasion. Despite its limitations for use in certain applications due to incompatibility with aromatic hydrocarbons, ketones, ozone, and sunlight, nitrile O-rings are used in a wide range of industries, including automobile and petroleum.

Due to it’s ability to be compounded for service over a temperature range of -65°F to +275°F, and it’s excellent resistance to petroleum products, Nitrile is the most widely used elastomer. Nitrile o-ring compounds can exhibit excellent compression set resistance, tear resistance, and abrasion resistance. These compounds do not exhibit good resistance to ozone, sunlight or weather.

ElastoTech-SouthWest Inc. (Crockett, TX)


Nitrile Rubber, frequently referred to as Buna-N, is a copolymer of butadiene and acrylonitrile. A number of polymers are commercially available with various monomer ratios. Those containing a high proportion of acrylonitrile have excellent resistance to petroleum oils and solvents, good tensile strength and abrasion resistance, but relatively poor low temperature flexibility. Decreasing acrylonitrile content yields great imrovement in the low temperature capability, but at the expense of poorer oil resistance.
