If your shop vacuum looks like mine, you probably aren’t getting its full performance, especially if it is more than a few years old. All those abrasions, cracks, and tears in the hose (despite several layers of duct tape) really do reduce the suction power. This hose measures 12 feet long, and is made of crush proof polyurethane. The inside of the hose has flattened ribs to reduce saw dust buildup which would reduce performance.
The upgrade kit includes a 12 ft x 1-1/2" ID polyurethane hose, a swivel cuff to help avoid hose kinking, a black “Vac Adapter” for connecting to any standard 2-1/4" inlet shop vacuum, a crevice tool for sucking dust out of the nooks and crannies in your shop, and a 4-1/2" wide claw tool for collecting debris.

Made of rugged HDPE plastic for long life. This kit comes with an adapter for 2-1/4" Tank Inlet. Adapters for 2-1/2" and 2-5/8" Tank Inlets are sold separately and accept the 2-1/4" Adapter.
