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 Bob Berry

This worked great for what I needed it for. I ordered this to use the various Dyson home appliances I have in my shop Vac. It worked great and sealed both the vacuum cleaner hose and the nozzle well. I tried it on my little dirt tool and it did NOT work, too big for her. But it worked great with Dyson and for the money it's worth I'm thrilled to be able to bring all my Dyson tools into my Shop Vac.
