-463 BLACK BUNA 50D O-RING

APG stocks the H50463, an AS568-463 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 16.955 in (430.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.505 in (444.63 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists hydraulic fluids, propane and butane, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with strong acids or ketones.

Typical settings include automotive, construction equipment, and general industrial maintenance.

This item is sold individually under part number H50463. Nominal inside diameter is listed as 17 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
