APG stocks the N70408, an AS568-408 black Neoprene (Chloroprene) 70 Shore A O-Ring measuring an inside diameter of 2.35 in (59.69 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.9 in (73.66 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
The material holds up against moderate petroleum oil exposure, mild acids, and ozone and weathering. That behavior comes from the compound itself: Neoprene (Chloroprene) is specified for a balanced combination of oil and weather resistance, strong performance in refrigeration circuits. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).
It sees regular use in general industrial, HVAC and refrigeration, and transit and rail.
This item is sold individually under part number N70408. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
