As a material, Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The material holds up against greases and lubricants, propane and butane, and water. Applications involving polar solvents or ozone and direct sunlight call for a different compound.
It sees regular use in general industrial maintenance, agricultural equipment, and fluid power.
