The material holds up against many alcohols, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in polar solvents or ozone and direct sunlight.

Maintenance and OEM teams specify it across construction equipment, general industrial maintenance, and hydraulic and pneumatic systems.
