As a material, Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. The compound resists greases and lubricants, petroleum-based oils, and propane and butane. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.

Typical settings include construction equipment, general industrial maintenance, and agricultural equipment.

Stocked as SB-H70035-100 and sold by the bag. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
