It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
As a material, Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and low compression set under sustained load. It resists petroleum-based oils, propane and butane, and many alcohols. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or ozone and direct sunlight are present.
You will find this material specified across general industrial maintenance, agricultural equipment, and hydraulic and pneumatic systems.
H2X71 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
