Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, low compression set under sustained load. The compound resists water, many alcohols, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or polar solvents call for a different compound.

Maintenance and OEM teams specify it across construction equipment, automotive, and agricultural equipment.

H3X56 ships individually. Unit weight is approximately 1.6678 g. 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.
