The adapter is useful in providing overhead gravity feed of paint to a conventional air spray paint gun having a bottom paint inlet port. The adapter includes a paint receptacle with a closable top lid and a bottom outlet. The receptacle can be transparent and bear volume indicia so that the amount of paint left in the receptacle can be estimated as spraying proceeds. The receptacle lid can be hinged and bear a releasable latch plate. The adapter also includes a conduit, the upper end of which is releasably connected to the receptacle at the outlet. The conduit depends from the receptacle and is adapted to support it in the upright position directly above an air spray paint gun. The conduit includes an upper laterally and downwardly adapted to flank the side of the spray gun curved portion, a transverse lower portion connected to the lower end of the upper portion and an upwardly directed central lower end bearing a connector to pivotably connect the conduit to the bottom paint inlet port of an air spray paint gun. Thus, the position of the paint receptacle and conduit can be changed by pivoting the conduit. Moreover, in one embodiment, the transverse portion is long enough to enable the upper portion of the conduit to be swung around the front of the nozzle to switch sides thereof. When the upper portion is also curved forwardly or rearwardly, such switching selectively centers the receptacle over the nozzle or handle to facilitate painting selected areas of the floor, ceiling or walls of a structure. The conduit can also include a stop cock or valve to close paint flow to the gun from the receptacle. The valve can be connected to and operated by the gun trigger.
