-457 BLACK CHLOROPRENE 70D O-RING

Part number N70457 is an AS568-457 black Neoprene (Chloroprene) 70 Shore A O-Ring supplied with an inside diameter of 13.975 in (354.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 14.525 in (368.94 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists ozone and weathering, refrigerants and ammonia, and sunlight and salt spray. That behavior comes from the compound itself: Neoprene (Chloroprene) is valued for dependable general-purpose sealing in exposed installations, a balanced combination of oil and weather resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving strong oxidizing acids or aromatic hydrocarbons call for a different compound.

You will find this material specified across marine equipment, weather sealing and enclosures, and HVAC and refrigeration.
