-392 BLACK BUNA 50D O-RING

H50392 is an AS568-392 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 22.94 in (582.68 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 23.36 in (593.34 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists greases and lubricants, water, and propane and butane. Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to automotive brake fluid or ketones will shorten service life.

Maintenance and OEM teams specify it across agricultural equipment, general industrial maintenance, and automotive.
