The Golden Jet Bulldog rotating nozzle from Enz USA operates with both recycled and freshwater. An integrated oil-free braking system results in low wear and tear operation, and in a controlled number of rotations. It is available in 1/2- to 1 1/4-inch connecting threads. The cleaning pipe diameter range starts from 2 1/2- through 24-inch pipe, depending on which nozzle specification suits the equipment. 877/369-8721; www.enzusainc.com.
