Introduction to NBR O - ring
Nitrile Butadiene Rubber (NBR) O - rings are one of the most commonly used sealing elements in various industries. NBR is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. The unique combination of these two monomers gives NBR O - rings excellent oil resistance, abrasion resistance, and mechanical properties.
They are widely used in automotive engines, hydraulic systems, pneumatic systems, and industrial machinery. In automotive applications, NBR O - rings can be found in fuel and oil systems, where they prevent leakage of fluids and maintain the proper functioning of the engine components. In hydraulic and pneumatic systems, they ensure the efficient transfer of power by sealing the pressurized fluid or gas within the system.
