APG stocks the N70311, an AS568-311 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 0.537 in (13.64 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 0.957 in (24.31 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, Neoprene (Chloroprene) offers good resilience across a moderate temperature band and strong performance in refrigeration circuits. The material holds up against ozone and weathering, sunlight and salt spray, and mild acids. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving aromatic hydrocarbons or strong oxidizing acids call for a different compound.
It sees regular use in general industrial, HVAC and refrigeration, and weather sealing and enclosures.
