A liquid paint spray gun of the type having a barrel through which compressed air flows to a nozzle, a liquid outlet valve centrally positioned within the barrel adjacent the nozzle for providing a low pressure supply of liquid to be entrained and atomized in the pressurized air at the nozzle for spraying onto a surface, and an improved liquid supply connector block for supplying liquid to the liquid outlet valve, the improved connector block comprising a hollow central body portion having non-stick internal surfaces and a plurality of external projections from the central body portion spaced therearound for supporting the hollow central body axially aligned within the barrel with space therearound for compressed air to flow to the nozzle end of the barrel; an orifice through one of the external projections sealingly connectable to a pressurized liquid supply; and a valve assembly formed in the connector block for interconnecting the liquid outlet valve in fluid communication with the hollow body portion, for holding it adjacent the nozzle of the spray gun and for permitting the outlet valve to be opened at the nozzle without leaking liquid into the barrel.
