Review on 🔴 POWERTEC 2.5" to 2.25" Reducer by John Hill

As others have said, this is not for a shop vacuum like a finned or craft vacuum. I think I can heat it up and stretch it, but what a bummer. I am converting a shop vacuum into a bag filter. So I used masking tape to increase the small diameter. I then used epoxy to attach it to the wall of the vacuum bath. J b weld. I made a border on the inside for a bar where you can attach the bag. The installation works fine. I used a HEPA filter set from a hardware store (bag and filter set). I blocked the hole in the motor with a piece of wood and epoxy. I'm not very good with epoxy but it works fine!
