-905 BLACK CHLOROPRENE 70D O-RING

The N70905 is an AS568-905 black Neoprene (Chloroprene) 70 Shore A O-Ring built to an inside diameter of 0.414 in (10.52 mm), a cross section of 0.072 in (1.83 mm), and an outside diameter of 0.558 in (14.17 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to ozone and weathering, mild acids, and refrigerants and ammonia. That behavior comes from the compound itself: Neoprene (Chloroprene) is widely chosen for good resilience across a moderate temperature band and dependable general-purpose sealing in exposed installations. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where strong oxidizing acids or chlorinated solvents are present.

Maintenance and OEM teams specify it across transit and rail, general industrial, and HVAC and refrigeration.
