As a material, Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The material holds up against many alcohols, propane and butane, and petroleum-based oils. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or ketones call for a different compound.
It sees regular use in agricultural equipment, hydraulic and pneumatic systems, and automotive.
H8X245 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
