Nitrile Rubber O-Rings (NBR)
Nitrile rubber is the general term for acrylonitrile butadiene terpolymer. The acrylonitrile content of nitrile sealing compounds varies considerably (18% to 50%) and influences the physical properties of the finished material. Nitrile rubber (NBR) is the general term for Acrylonitrile Butadiene Copolymer. It is the most widely used and economical elastomer.
The higher the acrylonitrile content, the better the resistance to oil and fuel. At the same time, elasticity and resistance to compression set is adversely affected. In view of these opposing realities, a compromise is often drawn, and a medium acrylonitrile content selected. Nitrile has good mechanical properties when compared with other elastomers and high wear resistance.
Both o-rings and gaskets can be made from Nitrile materials.

O ring is a type of seals with solid rubber materil and an O-shaped cross section.
Because its cross section is O-shaped, it is called O-shaped rubber ring. It is one of the most widely used hydraulic and pneumatic tran
