There is disclosed a spray head of improved design for airless spraying of liquids which utilizes a rotatable turret member to provide for reversing of the position of the orifice spray orifice tip for cleaning purposes. The rotatable turret member houses a conventional flat tip orifice without compromising the sealing, or the strength and useful life, of the spray assembly. To this end, a cylindrical turret member is formed of two sectored cylinders, one of which has a recess which receives a conventional flat tip. The two sectored cylinders are joined and secured in a cylindrical turret subassembly by interlocking keys and slots, preferably at opposite ends. The spray head also has a spray guard of generally conventional design with a key and arcuate slot connection to index the position of the rotatable turret member at cleaning and spraying positions.
