This material stands up to petroleum-based oils, many alcohols, and hydraulic fluids. Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs 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. It is not the right choice where ozone and direct sunlight or strong acids are present.

Typical settings include agricultural equipment, fluid power, and construction equipment.
