-458 BLACK CHLOROPRENE 70D O-RING

Ordered as N70458, this is an AS568-458 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 14.475 in (367.67 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 15.025 in (381.64 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against mild acids, ozone and weathering, and refrigerants and ammonia. That behavior comes from the compound itself: Neoprene (Chloroprene) is specified for good resilience across a moderate temperature band and inherent flame-retarding characteristics. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with chlorinated solvents or ketones.

Maintenance and OEM teams specify it across transit and rail, HVAC and refrigeration, and marine equipment.

Stocked as N70458 and sold individually. Unit weight is approximately 63.3019 g and nominal inside diameter is listed as 14 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to 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.
