Abstract: A mounting and cleaning adapter for use with a spray gun in which the spray tip is normally non-reversible and projects through a retaining nut in the paint spray position. The adapter comprises outer and inner sleeves for mounting the tip in a reversed cleaning position or in a spraying position. The outer sleeve is an elongated retaining nut which threadably engages to the spray gun for retaining the tip on the outer end of the inner sleeve, in the paint spray position and in the cleaning position within the outer sleeve. In the cleaning position, the inner sleeve receives the length and diameter of the barrel of the spray tip restraining the same within the outer sleeve. The fluid from the spray gun is forced backwards through the spray tip orifice dislodging accumulated debris.
