Part number 0284S625 is a black Buna-N (Nitrile) 50 Shore A O-Ring Cord Stock supplied with a cross section of 0.625 in (15.88 mm). An o-ring cord stock eliminates long lead times on large-diameter custom rings.

As a material, Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs and low compression set under sustained load. It resists many alcohols, propane and butane, and greases and lubricants. Applications involving strong acids or polar solvents call for a different compound.

It sees regular use in hydraulic and pneumatic systems, automotive, and fluid power.

0284S625 ships by the foot. 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.
