-142 BLACK CHLOROPRENE 70D O-RING

N70142 is an AS568-142 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 2.362 in (59.99 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.568 in (65.23 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against ozone and weathering, mild acids, and moderate petroleum oil exposure. That behavior comes from the compound itself: Neoprene (Chloroprene) is valued for strong performance in refrigeration circuits and dependable general-purpose sealing in exposed installations. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in chlorinated solvents or strong oxidizing acids.

Typical settings include HVAC and refrigeration, general industrial, and transit and rail.
