H70108 is an AS568-108 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.237 in (6.02 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.443 in (11.25 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
As a material, Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. The compound resists petroleum-based oils, many alcohols, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where strong acids or polar solvents are present.
Typical settings include construction equipment, fluid power, and hydraulic and pneumatic systems.
Stocked as H70108 and sold individually. Unit weight is approximately 0.182 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
