Dust Right Stacking Dust Port Adapter Set (3-Piece) – Interchangeable Vacuum Adapter for Dust Collection Hose & Tools – Glass Reinforced Polypropylene Dust Collectors for Woodworking

I needed to adapt the hose on my shop vac to fit my table saw the these adapters did the trick.H

I have to combine two of this adapter to make a good connection for my Dewalt table saw and Dewalt shopvac, but hey, I've bought many adapters and this is the only one that worked. Thanks!

Definitely good options in the set. The hose on my vac has a 1.5" OD and the 1.5" in this set doesn't fit super snug around it. Had to add a couple loops of electrical tape around the end of my hose to keep it from falling out.

These dust port adapters allow me to connect many of my woodworking tools to my large dust collector. The ability to adapt the hoses to the different sizes on my equipment allows me to keep the sawdust away from the home as I work out of the garage, tracking sawdust into the home does not go well for any of us. These dust port adapters also keep the sawdust out of my nose and lungs when connected to the dust collector.

I don't have a 4" device, so I don't know about that port The 2.5 fit the table saw., but NONE of the others fit any of the other tools (router (trim or full size), sander, miter, etc). It's possible my tools (off brands or older devices) are using non-standard sizes, but not from what I can tell from comparing specs.

Second set that I have bought. If you have a hose of any size then these suckers will fit it.

Works

I have 4 or 5 different brands of tools, and this set makes them all fit my 4" dust collector hose with no fuss.
