The compound resists greases and lubricants, petroleum-based oils, and many alcohols. Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or automotive brake fluid call for a different compound.

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