The Bulldog 37 Series Cross Jet Nozzle from Enz USA is engineered to operate with both fresh and recycled water. The cross jet design opens completely blocked lines, frozen pipe and interlaced root intrusions. An integrated oil-free braking system provides low-wear-and-tear operation, delivering a controlled number of rotations for efficient cleaning of roots, grease and solids. The nozzle is available in 1/2- and 3/4-inch connecting threads and can be used on pipes from 2.5 to 8 inches in diameter. 877/369-8721; www.enzusainc.com.
