Designed for controlled rotation and use with recycled water, the Primus Nozzle from USB-USA requires no lubrication or replacement of internal parts for at least one year. The nozzle is built from hardened stainless steel. A rotating head removes grease, light scale and roots; and 3D fluid mechanics in the propulsion unit efficiently flush out debris. This nozzle is available in 1/2-, 3/4-, 1- and 1 1/4-inch hose connections from 12 to 120 gpm. 844-285-5770; www.usb-usa.com.
