This material stands up to propane and butane, many alcohols, and petroleum-based oils. Buna-N (Nitrile) is valued for low compression set under sustained load, reliable performance in both static and dynamic service. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or polar solvents will shorten service life.

Common environments for this compound include construction equipment, general industrial maintenance, and fluid power.
