-233 BLACK BUNA 50D O-RING

Part number H50233 is an AS568-233 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 2.859 in (72.62 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.137 in (79.68 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to water, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).

It sees regular use in general industrial maintenance, automotive, and agricultural equipment.

H50233 ships individually. Nominal inside diameter is listed as 2 7/8 inch. 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.
