1/4 (.250) NEOPRENE CLOSED CELL SPONGE

Ordered as 0287250, this is a black Neoprene (Chloroprene) 70 Shore A O-Ring Cord Stock measuring a cross section of 0.25 in (6.35 mm). The o-ring cord stock provides continuous extruded stock for building one-off or oversized rings.

It resists refrigerants and ammonia, ozone and weathering, and moderate petroleum oil exposure. That behavior comes from the compound itself: Neoprene (Chloroprene) is known for dependable general-purpose sealing in exposed installations and strong performance in refrigeration circuits. Exposure to aromatic hydrocarbons or chlorinated solvents will shorten service life.

It sees regular use in general industrial, HVAC and refrigeration, and weather sealing and enclosures.

Reference part number 0287250 when ordering; the item is sold by the foot. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
