Buna-N (Nitrile) is specified here for low compression set under sustained load, strong abrasion and tear resistance. It resists petroleum-based oils, hydraulic fluids, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or polar solvents will shorten service life.

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

This item is sold individually under part number H3X41.5. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
