Dixon Valve and Coupling 1/2 In. Iron Male NPT End

The use of an Air King??safety clip or wire type retainer is necessary to ensure Air King??universal couplings will not become accidentally disconnected. This guarantees the fittings are properly connected because the safety pin will not go through the holes in mating flanges until couplings are locked in place. Only one Air King??safety clip or wire type retainer is required for each Air King??universal coupling.
