A lawn and garden sprayer having a tank, a hose and a dispensing wand. The dispensing wand is a tubular member having a fluid flow control valve at one end and a dispensing nozzle at the other. The dispensing nozzle is supported on a nozzle body which is press-fit into an end of the fluid dispensing tube where it is held by an interference fit to provide a fluid-tight joint. The nozzle body has a circumferential sealing surface and a knurled surface for preventing rotation of the nozzle body relative to the dispensing tube. A threaded portion is provided on the nozzle body for supporting a nozzle. A dispensing portion is covered by the nozzle and has a plurality of transverse apertures connecting to an axial fluid passage in the nozzle body to enable fluid contained in the tank to be dispensed through the nozzle.

A lawn and garden sprayer comprising: a tank for holding a reservoir of fluid to be dispensed; a wand connected in fluid communication with said tank for dispensing the fluid, said wand having a rigid tubular member defining a fluid passage, said wand having an aperture defining an inner diameter extending from said passage, through said rigid tubular member, to an outside of said wand; a nozzle connected with said rigid tubular member; and a nozzle support member interposed between said rigid tubular member and said nozzle, said nozzle support member having an axial bore connected in fluid communication between said passage of said rigid tubular member and said nozzle, having an insert portion received in press-fit engagement in said aperture through said rigid tubular member, and having a nozzle support portion adapted to receive said nozzle in slip fit engagement, said nozzle engaging said nozzle support portion, said insert portion including means located on a circumferential wall of said insert portion for sealing and inhibiting rotation of said nozzle support member within said wand, said means comprising: a substantially smooth portion having a larger outer diameter than the inner diameter of a corresponding portion of said wand such that a fluid-tight seal is formed therebetween upon assembly of said nozzle support member to said rigid tubular member; a textured portion having a larger diameter than the inner diameter of a corresponding portion of said wand such that rotation of said nozzle support member within said wand is inhibited upon assembly of said nozzle support member to said rigid tubular member; said smooth portion and said textured portion combining to prevent separation of said nozzle support member from said wand due to rotation of said nozzle support member with respect to said wand.
