1. An apparatus for supplying paint under pressure to a paint applicator, the apparatus comprising:
a spray gun comprising:
a housing;
a fluid pump having an outlet disposed within the housing; and
a spray tip assembly fluidly connected to the outlet of the fluid pump and having a bore for receiving and holding a spray tip, and a connector, wherein the spray tip assembly is able to be removed from and reattached to the spray gun via the connector; and
a spray gun adapter configured to be installed in the bore of the spray tip assembly in place of the spray tip by removing the spray tip from the bore of the spray tip assembly and installing the spray gun adapter into the bore of the spray tip assembly without removing the spray tip assembly from the spray gun, the spray gun adapter including an adapter inlet, an adapter outlet, and an adapter bore within the spray gun adapter that establishes a flow passage between the adapter inlet and the adapter outlet, so that when the spray gun adapter is installed in the bore of the spray tip assembly of the spray gun and the fluid pump is activated, a fluid flow is established from the fluid pump of the spray gun into the adapter inlet, through the adapter bore, to the adapter outlet, and thereby through the spray gun adapter to an applicator accessory connected to the adapter outlet.
