ABSTRACT:
A vacuum hose assembly includes an air inlet connector, a flexible hose, and rigid tube. Screw threads are provided on one end of the air inlet connector. Screw threads are also provided on one end of the rigid tube. The three components of the hose assembly are coupled by screwing one component to another. Therefore, the air inlet connector is coupled to the flexible hose by screwing the air inlet connector into the flexible hose so that the screw threads of the air inlet connector engage with the ridges of the flexible hose. Furthermore, the rigid tube is coupled to the flexible hose by screwing the rigid tube into the flexible hose so that the screw threads of the rigid tube engage with the ridges of the flexible hose.
