Product Specification

-
H50035 is an AS568-035 black Buna-N (Nitrile) 50 Shore A O-Ring with an inside diameter of 2.239 in (56.87 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.379 in (60.43 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to many alcohols, petroleum-based oils, and water. That behavior comes from the compound itself: Buna-N (Nitrile) delivers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong acids or ozone and direct sunlight.

You will find this material specified across construction equipment, automotive, and fluid power.

Stocked as H50035 and sold individually. Nominal inside diameter is listed as 2 1/4 inch. 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.
