8MM CS X 148MM ID BLACK BUNA 70D

The H8X148 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 148 mm (5.827 in), a cross section of 8 mm (0.315 in), and an outside diameter of 164 mm (6.46 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The material holds up against water, propane and butane, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or ketones will shorten service life.

Common environments for this compound include agricultural equipment, construction equipment, and hydraulic and pneumatic systems.
