Buna-N (Nitrile) is valued for strong abrasion and tear resistance, reliable performance in both static and dynamic service. The compound resists many alcohols, propane and butane, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or ozone and direct sunlight will shorten service life.
