This o-ring is supplied in AS568-113 black Buna-N (Nitrile) 50 Shore A with an inside diameter of 0.549 in (13.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.755 in (19.18 mm), catalogued under part number H50113. It creates a positive seal at flange, piston and rod interfaces without added hardware.
The compound resists petroleum-based oils, greases and lubricants, and water. Buna-N (Nitrile) is known for low compression set under sustained load and an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or ozone and direct sunlight will shorten service life.
It sees regular use in construction equipment, hydraulic and pneumatic systems, and general industrial maintenance.
H50113 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
