Abstract
Improved spray guns each have a spray head assembly comprising separate but interconnectable elements including a fluid nozzle, a fluid inlet fitting, a fluid nozzle retainer, an air nozzle and an air cap. The elements mount on an annular extension at a forward end of the gun body without any threaded attachment to the body, and because they are separate the fluid nozzle and fluid inlet fitting may conveniently be manufactured of a corrosion and wear resistant material to protect the same from fluid flowing therethrough. Also, the air cap threads onto the fluid nozzle retainer and not the gun body, so there is no danger of damaging any threads on the body which could otherwise require its replacement.
