-272 BLACK BUNA 50D O-RING

APG stocks the H50272, an AS568-272 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 9.484 in (240.89 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.762 in (247.95 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is known for low compression set under sustained load and an economical choice for high-volume maintenance programs. The compound resists many alcohols, greases and lubricants, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or ketones are present.

Common environments for this compound include general industrial maintenance, agricultural equipment, and hydraulic and pneumatic systems.

H50272 ships individually. Nominal inside diameter is listed as 9 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
