This o-ring is supplied in AS568-111 black Buna-N (Nitrile) 50 Shore A with an inside diameter of 0.424 in (10.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.63 in (16 mm), catalogued under part number H50111. It compresses into its gland to block fluid or gas migration across a joint.
The material holds up against many alcohols, water, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is valued 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).
Typical settings include automotive, construction equipment, and hydraulic and pneumatic systems.
Order part number H50111, sold individually. Unit weight is approximately 0.0004 g and nominal inside diameter is listed as 7/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
