Product Specification

-
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.

Order part number H50392, sold individually. Nominal inside diameter is listed as 23 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
