As a material, Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. This material stands up to propane and butane, greases and lubricants, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving strong acids or automotive brake fluid call for a different compound.

Typical settings include hydraulic and pneumatic systems, agricultural equipment, and automotive.
