-468 BLACK BUNA 70D O-RING

This o-ring is supplied in AS568-468 black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 19.455 in (494.16 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.005 in (508.13 mm), catalogued under part number H70MD468. It creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to many alcohols, propane and butane, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) offers low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where polar solvents or strong acids are present.

This o-ring is metal detectable for HACCP and foreign-body control programs. You will find this material specified across general industrial maintenance, agricultural equipment, and automotive.

This item is sold individually under part number H70MD468. Nominal inside diameter is listed as 19 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
