There is disclosed an improved spray tip particularly suited for airless pressured spraying utilizing a spray orifice member in a removable turret member that can be rotated to reverse the orifice for cleaning. The design permits rapid exchange of the turret member, permitting quick substitution of different sized orifice members. The turret member is sealed in the assembly with a thin plastic seal and a seal support which is compressed in the assembly by hand tightening. The seal and seal support are restrained in the spray tip against dislodgement during removal of the turret member. A tee seal is provided which has a flange of reduced diameter which seats against the end of the spray gun to insure complete sealing with hand tightening of the retainer nut. The spray tip also includes a low friction bearing washer between its housing and retaining nut which, in cooperation with the tee seal, permits rotation of the spray tip without loosening its retainer nut.
