  • High performance nozzle
    Publication number: 20040256497
    Abstract: What is new about this nozzle is its ability to extend the reach of a fluid stream from a pressurized hose by means of low-friction design and nozzle aperture extension. The combination of low friction design and aperture extension produces an effect which is superior to that which might be anticipated by adding an extension to a hose. The nozzle is made of strong, lightweight, rigid materials. The extended stream reach exceeds the length of the long nozzle itself.
