Abstract: A dual closure nozzle for use with a hose carrying a liquid under pressure. The dual closure nozzle is made up of an inner delivery conduit attached to an end cap and threaded within an outer sleeve having a nozzle head. The dual closure nozzle is configured to have two different stop positions and to be adjustable between these two stop positions and a variety of open positions. When a liquid is forced through the nozzle, the flow of the liquid can then be adjusted from a first stop position, where no liquid passes out of the nozzle, through a variety of open position spray patterns to a second stop position. This configuration thus provides a nozzle that can be closed by turning the outer sleeve portion of the nozzle in either of two directions, and prevents spray from wetting the person utilizing the device.
