-271 BLACK CHLOROPRENE 70D O-RING

This o-ring is supplied in AS568-271 black Neoprene (Chloroprene) 70 Shore A built to an inside diameter of 9.234 in (234.54 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.512 in (241.6 mm), catalogued under part number N70271. It remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against mild acids, ozone and weathering, and sunlight and salt spray. That behavior comes from the compound itself: Neoprene (Chloroprene) is known for good resilience across a moderate temperature band and inherent flame-retarding characteristics. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with strong oxidizing acids or chlorinated solvents.

You will find this material specified across HVAC and refrigeration, marine equipment, and transit and rail.

Reference part number N70271 when ordering; the item is sold individually. Unit weight is approximately 10.2584 g and nominal inside diameter is listed as 9 1/4 inch.
