The H70417 is an AS568-417 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 3.475 in (88.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.025 in (102.24 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Buna-N (Nitrile) is specified here for low compression set under sustained load and economical choice for high-volume maintenance programs. Expect good resistance to water, propane and butane, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or polar solvents will shorten service life.
You will find this material specified across construction equipment, automotive, and general industrial maintenance.
H70417 ships individually. Unit weight is approximately 14.024 g and nominal inside diameter is listed as 3 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need?
