8MM (.315) BUNA-N ORING CORD 70 DURO

0M284B8 is a black Buna-N (Nitrile) 70 Shore A O-Ring Cord Stock measuring a cross section of 0.315 in (8 mm). In service, this o-ring cord stock lets you fabricate a custom-size seal on site by cutting and splicing to the required circumference.

Expect good resistance to petroleum-based oils, water, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Exposure to polar solvents or ketones will shorten service life.

It sees regular use in hydraulic and pneumatic systems, agricultural equipment, and general industrial maintenance.
