BLUESTAR sewer cleaning nozzles from Sewer Pro Shop are manufactured with optimized 3-D hydromechanics by Intersewer. Pressurized water is first divided by a conically-shaped piece and smoothly turned around in the nozzle chamber before being guided directly into the stainless steel nozzle inserts by means of five-axial CNC precision manufacturing. Ceramic nozzle inserts are available for use in conjunction with recycled water. The nozzles are neither bonded nor screwed together. They use case-hardened steel and stainless steel components. 470/592-1717; www.sewerproshop.com.
