How to Make Vacuum Attachment Connections Tighter

It’s frustrating when shop vacuum couplings and attachments become worn and no longer form a good friction fit to the hose. To snug things up again, I spray the inside of the coupling area with a rubberized material that you can find at home centers or auto parts stores. A few coats of this stuff will restore a good connection, and it sticks well to plastic.
