APG stocks the N70260, an AS568-260 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 6.484 in (164.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.762 in (171.75 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, Neoprene (Chloroprene) is widely chosen for strong performance in refrigeration circuits and good resilience across a moderate temperature band. It resists sunlight and salt spray, ozone and weathering, and refrigerants and ammonia. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or strong oxidizing acids will shorten service life.
Maintenance and OEM teams specify it across marine equipment, general industrial, and transit and rail.
N70260 ships individually. Unit weight is approximately 7.4 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.
