I had an extra Dewalt metal floor wand laying around and needed one for my Flex dust collector. I removed the Dewalt Airlock adapter that is fit into the end of the wand and replaced it with this one so I can connect easily.
The metal floor wand has an ID of appx 35mm so this would work with other tubes of the same size as well.
This also works with the Cen-Tec type antistatic hoses that have the same type of quick connect hose end.
