APG stocks the N70364, an AS568-364 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 6.725 in (170.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.145 in (181.48 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
This material stands up to moderate petroleum oil exposure, ozone and weathering, and mild acids. That behavior comes from the compound itself: Neoprene (Chloroprene) offers strong performance in refrigeration circuits and inherent flame-retarding characteristics. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in aromatic hydrocarbons or ketones.
Maintenance and OEM teams specify it across general industrial, weather sealing and enclosures, and transit and rail.
Stocked as N70364 and sold individually. Unit weight is approximately 17.3046 g and nominal inside diameter is listed as 6 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need?
