There is disclosed an airless spray head having a rotatable turret orifice tip holder with a floating turret seal preloaded with a compression spring within a spray head body having a distal circular rim, a through longitudinal passageway and an intersecting orthogonal bore which receives the cylindrical turret. A retainer nut surrounds and receives the spray head body which is captured by the circular rim, and a low friction washer is located between the rim and the retainer nut. The compression spring is biased against the upstream face of the turret seal by a spring retainer with a boss on its downstream face and an annular groove on its upstream face in which an annular sealing washer is permanently received. The compression spring is mounted on the downstream boss and retained thereon by spring detents of the boss. A second annular sealing washer is located between the downstream face of the retainer and the end of the spray head body. The seals of this spray head are compressed entirely by hand tightening of the retainer nut and the spray head can be easily disassembled and components replaced by loosening of the retainer nut.
