This is the perfect adapter for your vacuum tube to connect up a 4” suction hose for those hard to get to and smaller jobs. One side, of course, connects to your suction hose. Just slip over the open end and put on a king Clamp. The other side is open to the atmosphere (free air) so you don’t overheat your vacuum pump. It has a safety grid on the inside to protect your workers, please see photo. It is made of steel and is zinc plated.
