-416 BLACK CHLOROPRENE 70D O-RING

The N70416 is an AS568-416 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 3.35 in (85.09 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.9 in (99.06 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists sunlight and salt spray, mild acids, and refrigerants and ammonia. That behavior comes from the compound itself: Neoprene (Chloroprene) is valued 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). Exposure to chlorinated solvents or ketones will shorten service life.

You will find this material specified across transit and rail, HVAC and refrigeration, and general industrial.

This item is sold individually under part number N70416. Nominal inside diameter is listed as 3 3/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
