It resists propane and butane, water, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

Maintenance and OEM teams specify it across general industrial maintenance, agricultural equipment, and construction equipment.
