The N70415 is an AS568-415 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 3.225 in (81.92 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.775 in (95.89 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to ozone and weathering, mild acids, and sunlight and salt spray. That behavior comes from the compound itself: Neoprene (Chloroprene) is widely chosen for strong performance in refrigeration circuits and good resilience across a moderate temperature band. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong oxidizing acids or ketones.
Maintenance and OEM teams specify it across HVAC and refrigeration, transit and rail, and marine equipment.
N70415 ships individually. Nominal inside diameter is listed as 3 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
