One-piece stainless steel cleaning nozzles from USB – Sewer Equipment Corporation aren’t bonded or screwed together, enhancing strength and reducing the chances of failure under pressure. Their Advanced Optimized 3-D Hydro Mechanics®, located in the lower part of the chamber, eliminate pressure in the upper portion of the nozzle and prevent explosion in a sewer line or manhole. The water coming from a pressurized hose is immediately guided directly into channels and smoothly directed into one-piece ceramic nozzle inserts, which don’t require winglets or flow-straighteners due to the hydromechanics in and out of the chamber, resulting in an efficient jet pattern. They are engineered and manufactured according to DIN EN ISO 9001:2000. 866/408-2814; www.usbsec.com.
