As a material, Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The material holds up against many alcohols, propane and butane, and petroleum-based oils. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or ketones call for a different compound.

It sees regular use in agricultural equipment, hydraulic and pneumatic systems, and automotive.
