POWERTEC 70322 4 Inch to 2-1/2 Inch Reducer and 4 Inch Dust Control Flex Cuff with Stainless Steel Hose Clamps, Dust Collection Fitting for Woodworking Dust Collection Hose and Dust Ports, 1 Set

It’s definitely fit the collector and reduces it easily, installation was easy connection is tight. I think it’s a good value for what it does. The rubber is very durable and quality. It should last a long time.

Well made for a basement 3D printed item. Works fine. Fair price. Filled a need perfectly, and I appreciate the ability to support other makers. Need: I do amateur digital electronics and solder at a bench in a home office a lot. I built a custom exhaust fan / vent setup using a home "grow" fan and shop vac 2.5" ducting. The fan and exhaust are 4". I exhaust everything out the window through a dryer fitting and baffle. The 2.5 ducting gives me velocity and 4" gives me the volume. It works well under my microscope / soldering stage.

I would rather the 4 inch side was slightly larger, rather than the same size as the pipe, so that it would simply fit over the pipe to just be banded down, but the flex cuff accomplished that task. I was just happy to find a product that accomplished what I needed, which was to vent toxic fumes from a 3-D printer to the outside through a dryer vent.

fits my bandsaw perfect

Works great on several tools I have in my garage. Make connections easy.

Form, fit, & function as advertised

Perfect fit. I need to be able to attach my 2-1/2" dust collection hose to my Dewalt DWE7491 and my SawStop CNS175 table saws. It is now effortless. With this adapter clamped on the SawStop I can swap the hose in seconds from one saw to the other.

I have the DeWalt 735 planer and use a series of shop vacs for dust collection, but all the connection I purchased were the exact same size as what's on the planer, so I couldn't attach the hose to the planer. This device is a perfect fit OVER the planer dust port, fasten securely with hose clamps to both sides and saves me a lot of time in cleanup. It is flexible, but it's also short so the flexibility isn't a huge benefit. Still, great way to connect two hoses and even reducers to a dust port and probably good between with larger dust collection systems.

Muy buena calidad

I bought this with the Powertec 70169 mini gulp hood. Fits directly to that and allows you to connect a vacucum hose with relative ease.

Cumple su función.

Does what I needed it to do. Good quality, does the job! Definitely would recommend purchasing.

perfect fit.
