-231 BLACK CHLOROPRENE 70D O-RING

This o-ring is supplied in AS568-231 black Neoprene (Chloroprene) 70 Shore A with an inside diameter of 2.609 in (66.27 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.887 in (73.33 mm), catalogued under part number N70231. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Neoprene (Chloroprene) delivers good resilience across a moderate temperature band and inherent flame-retarding characteristics. It resists ozone and weathering, sunlight and salt spray, and refrigerants and ammonia. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or chlorinated solvents will shorten service life.

It sees regular use in weather sealing and enclosures, HVAC and refrigeration, and marine equipment.

This item is sold individually under part number N70231. Unit weight is approximately 3.01 g and nominal inside diameter is listed as 2 5/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
