Patent ID: 6978944

Claim:
In a reversible spray tip unit adapted to be secured to the discharge end of a spray gun for hydraulically atomizing and spraying liquid paint, the spray tip unit including a spray tip unit housing, an axially rotatable cylindrically shaped turret member with a spray tip nozzle arranged in a diametric fluid bore therein, the turret member being disposed in a complementary shaped bore of the unit housing arranged transverse to the flow of paint and having a T-shaped handle at an end of the turret member for the rotation thereof, and a cylindrically shaped saddle seal received in an axial bore in the unit housing and having a cylindrically shaped sealing face mating with the cylindrical shape of the turret member at the diametric fluid bore housing the spray tip nozzle, the saddle seal being provided with an axial fluid bore for communication between the spray gun discharge and the rotatable turret member, the improvement comprising: an insertion/orientation tool for inserting said saddle seal into the axial bore therefor in said unit housing and orienting the saddle seal in the axial bore to align the sealing face thereof with the cylindrically shaped bore in the unit housing for said turret member, said orientation being accomplished by providing the fluid bore in said saddle seal with a keyway shape and the insertion/orientation tool with a key adapted to be keyed to the keyway shape of the saddle seal fluid bore, whereby the rotation of said insertion/orientation tool rotates said saddle seal.
