-114 BLACK BUNA 70D O-RING

H70114 is an AS568-114 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.612 in (15.54 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.818 in (20.78 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to many alcohols, petroleum-based oils, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is known for low compression set under sustained load and an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C).

You will find this material specified across automotive, general industrial maintenance, and fluid power.
