-471 BLACK CHLOROPRENE 70D O-RING

Ordered as N70471, this is an AS568-471 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 21.955 in (557.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 22.505 in (571.63 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to moderate petroleum oil exposure, sunlight and salt spray, and ozone and weathering. That behavior comes from the compound itself: Neoprene (Chloroprene) is valued for a balanced combination of oil and weather resistance, inherent flame-retarding characteristics. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with chlorinated solvents or ketones.

You will find this material specified across transit and rail, HVAC and refrigeration, and weather sealing and enclosures.
