Buna-N (Nitrile) offers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The material holds up against propane and butane, water, and petroleum-based oils. 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.

Maintenance and OEM teams specify it across construction equipment, agricultural equipment, and general industrial maintenance.

Stocked as SB-H3X22-50 and sold by the bag. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
