-108 BLACK BUNA 70D O-RING

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.
