A two-piece nozzle for use on hand actuated pump dispensers is disclosed. The nozzle features a tubular member, which may be a part of the main body of the pump, having a circular, planar face at its terminal end. A hollow bore extending through the tubular member and the hollow face is in liquid passage communication with a recess in the planar face. A cap is rotatably mounted to the tubular member and has an end wall with a planar inside surface which will form an interface with the circular planar face of the tubular member. Radially displaced from the center axis of the circular skirt is a dispensing orifice which is registerable with the recess present in the planar face of the tubular member. A sealing boss surrounds the dispensing orifice and bore to provide a liquid-tight seal with the planar face when the orifice is not in registration with the recess. Mounting structure is provided on the cap and tubular member for achieving a rotating mount of the cap to the tubular member.
