-373 BLACK CHLOROPRENE 70D O-RING

Part number N70373 is an AS568-373 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 8.975 in (227.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.395 in (238.63 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists mild acids, refrigerants and ammonia, and ozone and weathering. That behavior comes from the compound itself: Neoprene (Chloroprene) is widely chosen for strong performance in refrigeration circuits and dependable general-purpose sealing in exposed installations. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving strong oxidizing acids or aromatic hydrocarbons call for a different compound.

You will find this material specified across weather sealing and enclosures, transit and rail, and marine equipment.

This item is sold individually under part number N70373. Unit weight is approximately 22.94 g and nominal inside diameter is listed as 9 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
