Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs and low compression set under sustained load. The compound resists many alcohols, propane and butane, and water. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or strong acids. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

It sees regular use in general industrial maintenance, agricultural equipment, and automotive.
