-388 BLACK CHLOROPRENE 70D O-RING

This o-ring is supplied in AS568-388 black Neoprene (Chloroprene) 70 Shore A supplied with an inside diameter of 18.953 in (481.41 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 19.373 in (492.07 mm), catalogued under part number N70388. It compresses into its gland to block fluid or gas migration across a joint.

The compound resists refrigerants and ammonia, mild acids, and ozone and weathering. That behavior comes from the compound itself: Neoprene (Chloroprene) is specified for inherent flame-retarding characteristics and strong performance in refrigeration circuits. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or strong oxidizing acids.

It sees regular use in marine equipment, general industrial, and transit and rail.

Stocked as N70388 and sold individually. Unit weight is approximately 47.8164 g and nominal inside diameter is listed as 19 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
