Review on Universal Shop Vacuum Hose Adapter - WORKSHOP Wet/Dry Vacs Vacuum Adapter WS25011A 2-1/2-Inch to 1-1/4-Inch for Enhancing Shop Vacuum Accessories by David Lamfers

I wanted something to clear PVC pipe from air conditioning and just bought a Craftsman Wet/Vac and didn't know it came with a 2.5" hose is supplied, so it's too big for a 1" hose. (External dimension) PVC pipe, like my old 1 1/4" hose. This mount fits right onto the end of a 2.5" hose and fits perfectly on PVC pipe and also allows me to use other tools that are designed for 1 1/4 hose. I didn't give a full 5 stars just because it's a bit flimsy and doesn't feel that durable, but for the price it's a great bargain.
