H70202 is an AS568-202 black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 0.234 in (5.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.512 in (13 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. It resists petroleum-based oils, water, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving polar solvents or automotive brake fluid call for a different compound.
Common environments for this compound include general industrial maintenance, automotive, and agricultural equipment.
Stocked as H70202 and sold individually. Unit weight is approximately 0.3642 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
