-125 BLACK CHLOROPRENE 70D O-RING

N70125 is an AS568-125 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 1.299 in (32.99 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.505 in (38.23 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against refrigerants and ammonia, mild acids, and ozone and weathering. That behavior comes from the compound itself: Neoprene (Chloroprene) is valued for strong performance in refrigeration circuits and good resilience across a moderate temperature band. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in chlorinated solvents or strong oxidizing acids.

You will find this material specified across marine equipment, weather sealing and enclosures, and general industrial.

Stocked as N70125 and sold individually. Unit weight is approximately 0.84 g and nominal inside diameter is listed as 1 5/16 inch. Review your operating media and conditions against this specification before installation. 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.
