N70028 is an AS568-028 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 1.364 in (34.65 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.504 in (38.2 mm). In service, 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 inherent flame-retarding characteristics, balanced combination of oil and weather resistance. Expect good resistance to mild acids, ozone and weathering, and sunlight and salt spray. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to aromatic hydrocarbons or ketones will shorten service life.
Maintenance and OEM teams specify it across marine equipment, general industrial, and transit and rail.
Order part number N70028, sold individually. Unit weight is approximately 0.3991 g and nominal inside diameter is listed as 1 3/8 inch. Review your operating media and conditions against this specification before installation.
