An air stabilizing copper cap for a spray gun is essentially comprised of a plurality of axial holes provided on the periphery of the copper air cap, and a stopper ring being formed in the front end of the copper air cap so that a buffer chamber is created in the space between the front edge of the holes and the stopper; a hollow threaded tube is axially formed in the rear of the copper air cap, and both inner and outer threads are respectively provided in the space of the front end of the copper air cap and where external of the threaded tube to secure the nozzle head and the copper air cap onto the front end of the spray gun; so that high pressure air ejecting through the holes of the copper air cap is restricted in the buffer chamber before the stopper for pressure reduction to allow the release of stabilized air flow.
