An angularly adjustable liquid outlet nozzle for directing a stream of fluid under pressure into a body of fluid has a unitary body with an inlet opening at one end communicating with a mixing chamber through a venturi air inlet, and an outlet opening at the other end in which is seated a directional ball outlet between a pair of low friction bearing and sealing rings. A spring maintains a sealing engagement between the low friction rings and the ball outlet so that the latter may be directionally adjusted without interrupting the seal.
