It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and low compression set under sustained load. This material stands up to hydraulic fluids, many alcohols, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in strong acids or ketones.

Maintenance and OEM teams specify it across hydraulic and pneumatic systems, construction equipment, and automotive.

Stocked as H50410 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
