-128 BLACK CHLOROPRENE 70D O-RING

The N70128 is an AS568-128 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 1.487 in (37.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.693 in (43 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Neoprene (Chloroprene) is specified here for good resilience across a moderate temperature band and dependable general-purpose sealing in exposed installations. The compound resists sunlight and salt spray, moderate petroleum oil exposure, and refrigerants and ammonia. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to chlorinated solvents or aromatic hydrocarbons will shorten service life.

Common environments for this compound include HVAC and refrigeration, transit and rail, and general industrial.

Order part number N70128, sold individually. Unit weight is approximately 0.9587 g and nominal inside diameter is listed as 1 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
