-909 BLACK CHLOROPRENE 70D O-RING

The N70909 is an AS568-909 black Neoprene (Chloroprene) 70 Shore A O-Ring with an inside diameter of 0.706 in (17.93 mm), a cross section of 0.097 in (2.46 mm), and an outside diameter of 0.9 in (22.86 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to ozone and weathering, mild acids, and sunlight and salt spray. That behavior comes from the compound itself: Neoprene (Chloroprene) is widely chosen for dependable general-purpose sealing in exposed installations and inherent flame-retarding characteristics. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in chlorinated solvents or aromatic hydrocarbons.

Common environments for this compound include general industrial, weather sealing and enclosures, and HVAC and refrigeration.

N70909 ships individually. Unit weight is approximately 0.44 g and nominal inside diameter is listed as 9/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
