Part number N70358 is an AS568-358 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 5.6 in (142.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.02 in (152.91 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to ozone and weathering, refrigerants and ammonia, 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. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ketones or strong oxidizing acids.

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