N70419 is an AS568-419 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 3.725 in (94.62 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.275 in (108.59 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
It resists mild acids, sunlight and salt spray, and ozone and weathering. That behavior comes from the compound itself: Neoprene (Chloroprene) is specified for good resilience across a moderate temperature band and inherent flame-retarding characteristics. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong oxidizing acids or chlorinated solvents.
Typical settings include general industrial, transit and rail, and marine equipment.
N70419 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
