-247 BLACK CHLOROPRENE 70D O-RING

Part number N70247 is an AS568-247 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 4.609 in (117.07 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.887 in (124.13 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Neoprene (Chloroprene) is widely chosen for inherent flame-retarding characteristics and good resilience across a moderate temperature band. The material holds up against sunlight and salt spray, refrigerants and ammonia, and ozone and weathering. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong oxidizing acids or chlorinated solvents.

Common environments for this compound include weather sealing and enclosures, general industrial, and HVAC and refrigeration.

Stocked as N70247 and sold individually. Unit weight is approximately 5.1966 g and nominal inside diameter is listed as 4 5/8 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
