4MM CS X 7MM ID BLACK BUNA 70D

The H4X7 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 7 mm (0.276 in), a cross section of 4 mm (0.157 in), and an outside diameter of 15 mm (0.59 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to hydraulic fluids, propane and butane, and many alcohols. Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or strong acids call for a different compound.

Common environments for this compound include fluid power, construction equipment, and automotive.
