Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. The material holds up against greases and lubricants, water, and petroleum-based oils. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with polar solvents or ketones. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

Typical settings include automotive, agricultural equipment, and construction equipment.
