Part number H50375 is an AS568-375 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 9.475 in (240.67 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.895 in (251.33 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, low compression set under sustained load. Expect good resistance to greases and lubricants, petroleum-based oils, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or polar solvents will shorten service life.
You will find this material specified across general industrial maintenance, agricultural equipment, and hydraulic and pneumatic systems.
Stocked as H50375 and sold individually. Nominal inside diameter is listed as 9 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
