-143 BLACK CHLOROPRENE 70D O-RING

APG stocks the N70143, an AS568-143 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 2.425 in (61.6 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.631 in (66.83 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to refrigerants and ammonia, sunlight and salt spray, and mild acids. Neoprene (Chloroprene) is widely chosen for dependable general-purpose sealing in exposed installations and strong performance in refrigeration circuits. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to chlorinated solvents or aromatic hydrocarbons will shorten service life.

You will find this material specified across marine equipment, HVAC and refrigeration, and weather sealing and enclosures.
