-473 BLACK BUNA 70D O-RING

This o-ring is supplied in AS568-473 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 23.94 in (608.08 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 24.49 in (622.05 mm), catalogued under part number H70473. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against hydraulic fluids, propane and butane, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for strong abrasion and tear resistance, reliable performance in both static and dynamic service. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or automotive brake fluid call for a different compound.

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

H70473 ships individually. Unit weight is approximately 90.5598 g. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
