1.5MM CS X 8MM ID BLACK BUNA 70D

Ordered as H1.5X8, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 8 mm (0.315 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 11 mm (0.43 in). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists greases and lubricants, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).

You will find this material specified across fluid power, hydraulic and pneumatic systems, and general industrial maintenance.

This item is sold individually under part number H1.5X8. Unit weight is approximately 0.0674 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
