-470 BLACK BUNA 50D O-RING

Part number H50470 is an AS568-470 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 20.955 in (532.26 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 21.505 in (546.23 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against hydraulic fluids, petroleum-based oils, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).

Typical settings include hydraulic and pneumatic systems, general industrial maintenance, and fluid power.

This item is sold individually under part number H50470. Nominal inside diameter is listed as 21 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
