There is provided a reversible spray tip (10) unit for an airless spray gun having an axially rotatable cylindrically shaped turret member (12) with the spray tip nozzle arranged in a diametric fluid bore (22) therein, the turret member (12) being disposed in a complementary shaped bore of a housing (14) and arranged transverse to the flow of paint, and a saddle seal (16) received axially in the housing (14) and having a cylindrically shaped sealing (34) face mating with the cylindrical shape of the turret member (12) at the diametric fluid bore housing the spray tip nozzle. Upon assembly of the disassembled reversible spray tip unit, the saddle seal (16) is quickly inserted into the housing and accurately oriented so that its sealing face (34) is aligned with the cylindrically shaped bore in the housing for the turret member (12) by means of an insertion/orientation tool (42) which is adapted to be keyed to the fluid bore of the saddle seal (16). |
