Abstract
A reversible spray tip assembly having a housing formed with a longitudinal bore and a transverse bore, a cylindrical turret having a spray tip orifice rotatably and removably supported in the transverse housing bore, and a floating seal disposed in the longitudinal housing bore and having a concave sealing face adapted for sealing engagement with the turret. The spray tip assembly includes a seal adaptor disposed in the longitudinal housing bore upstream of the floating seal which, upon securement of the spray tip assembly onto a supply line by a threaded coupling, causes the seal to be forced into predetermined initial sealing contact with the turret regardless of how tightly the coupling is screwed onto the supply line.
