The Reducer Cuff from Southland Tool is designed to solve the problem of large rocks and material becoming stuck in 8-inch tubes, top-mounted elbows, horizontal hoses and telescopic extensions. Blocked debris can cut off suction flow and overheat the pump, requiring workers to stop to disassemble tubes to locate and remove the blockage. The 8-by-6-inch unit attaches to the 8-inch flat flange or other connection and then reduces to a 6-inch steel pipe with a 6-inch Kanaflex 180 AR hose bolted to it. This allows the user to dig and not damage utility lines while avoiding sucking up anything larger than 6 inches. It weighs 10 pounds and is 17 inches tall. 714-632-8198; www.southlandtool.com.
