Ordered as N70323, this is an AS568-323 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 1.287 in (32.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.707 in (43.36 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Neoprene (Chloroprene) is widely chosen for inherent flame-retarding characteristics, a balanced combination of oil and weather resistance. The material holds up against refrigerants and ammonia, sunlight and salt spray, and moderate petroleum oil exposure. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or chlorinated solvents will shorten service life.
Common environments for this compound include transit and rail, marine equipment, and weather sealing and enclosures.
Reference part number N70323 when ordering; the item is sold individually. Unit weight is approximately 3.735 g. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
