-158 BLACK CHLOROPRENE 70D O-RING

APG stocks the N70158, an AS568-158 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 4.737 in (120.32 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.943 in (125.55 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Neoprene (Chloroprene) is known for inherent flame-retarding characteristics and strong performance in refrigeration circuits. This material stands up to mild acids, moderate petroleum oil exposure, and ozone and weathering. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).

Common environments for this compound include general industrial, marine equipment, and transit and rail.

N70158 ships individually. Unit weight is approximately 2.91 g. 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.
