N70170 is an AS568-170 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 7.737 in (196.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.943 in (201.75 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
As a material, Neoprene (Chloroprene) is valued for good resilience across a moderate temperature band and inherent flame-retarding characteristics. Expect good resistance to ozone and weathering, moderate petroleum oil exposure, and refrigerants and ammonia. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or chlorinated solvents will shorten service life.
Common environments for this compound include weather sealing and enclosures, transit and rail, and HVAC and refrigeration.
N70170 ships individually. Unit weight is approximately 4.71 g and nominal inside diameter is listed as 7 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
