-342 BLACK CHLOROPRENE 70D O-RING

Ordered as N70342, this is an AS568-342 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 3.6 in (91.44 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.02 in (102.11 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists mild acids, ozone and weathering, and moderate petroleum oil exposure. That behavior comes from the compound itself: Neoprene (Chloroprene) delivers inherent flame-retarding characteristics and dependable general-purpose sealing in exposed installations. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C).

Maintenance and OEM teams specify it across marine equipment, general industrial, and transit and rail.
