APG stocks the H50175, an AS568-175 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 8.987 in (228.27 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.193 in (233.5 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to hydraulic fluids, petroleum-based oils, and water. Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving polar solvents or ketones call for a different compound.

Maintenance and OEM teams specify it across construction equipment, hydraulic and pneumatic systems, and general industrial maintenance.
