-468 BLACK CHLOROPRENE 70D O-RING

Ordered as N70468, this is an AS568-468 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 19.455 in (494.16 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 20.005 in (508.13 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists sunlight and salt spray, ozone and weathering, and moderate petroleum oil exposure. That behavior comes from the compound itself: Neoprene (Chloroprene) is known for good resilience across a moderate temperature band, a balanced combination of oil and weather resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to chlorinated solvents or strong oxidizing acids will shorten service life.

You will find this material specified across marine equipment, transit and rail, and general industrial.

Order part number N70468, sold individually. Unit weight is approximately 84.6734 g and nominal inside diameter is listed as 19 1/2 inch.
