There is disclosed an improved spray tip particularly suited for airless pressured spraying utilizing a spray orifice member in a removeable turret member that can be rotated to reverse the orifice for cleaning. The design overcomes difficulties with prior art spray tips of this construction by the use of a thin resilient seal which is located between the turret member and a seal support which is compressed in the assembly. The use of the thin seal achieves a fluid tight seal that prevents leaking even of low viscosity liquids while avoiding the seizure problems which have characterized plastic seals of prior devices. The turret member is removeable without disassembly of the spray tip or its guard, thereby permitting facile interchanging of turret members with differently sized orifices.
