-471 BLACK BUNA 70D O-RING

APG stocks the H70471, an AS568-471 black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 21.955 in (557.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 22.505 in (571.63 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to hydraulic fluids, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) delivers 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). Exposure to automotive brake fluid or strong acids will shorten service life.

It sees regular use in general industrial maintenance, hydraulic and pneumatic systems, and fluid power.
