POWERTEC 70136 4" to 2-1/2" Cone Reducer, Dust Collection Fittings for Dust Collection Hose to Hose Connection

Great fit to reduce my 4" dust collection system down to 2 1/2" with a firm but not too tight friction fit with the appropriate 4" female adapter. Makes switching my 4" and 2 1/2" systems quick and easy.

Fit perfect and work great on my fume extractor.

This was an interesting buy. I was told the fitting was unavailable, but could be computer printed. It turns out that I didn't need it, but it was too interesting to pass up, and inexpensive. So, I accepted. It appears to be accurate, sturdy and perfectly acceptable for the task. The surface texture is a little bit bumpy, compared to a smooth PVC fitting, but well within acceptable limits. I am going to keep this around for show & tell.

Attached it to my new Bauer bandsaw. Had to get a 4” coupler from home depot but it’s perfect otherwise wise.

excellent product

Perfect connection! Thick and the perfect size.

I bought a new Laguna 14 Twelve Bandsaw and needed to be able to connect my Rigid Shop Vac for dust collection. I purchased this PowerTec reducer because I knew it would connect perfectly to my shop vac. And I knew ahead of time that it would be the same diameter as my 4” dust port on my Laguna, so I knew it wasn’t going to simply slide over my dust port. But I had seen videos where other folks had cut a small section of 4 inch PVC pipe (Schedule 40) to use as a coupling. I did the same and it worked perfectly. I will say though that I had to lightly sand the inside of the 4” PVC pipe to reduce the wall thickness by just a hair so that it would slide on. It was not difficult at all. I didn’t have a Spindle Sander at the time so I glued a 2 inch strip of 150 grit sandpaper to a 1/2 “ dowel and installed it in my drill press. After running it around the inside of the PVC several times with the drill press set on medium speed, it was just enough to allow the PVC to slide over the dust port. You may not have this problem. The Laguna has an exceptionally thick powder coating finish on it which is very durable but probably also makes the outside diameter of the dust port just a hair thicker than some other brands, which explains why the 4 inch PVC needed just a tiny bit of sanding of the inside to make it fit.You can get a smaller length of 4 inch PVC at both bog box stores if you don't already have some or don't have a need to buy a full 10 foot stick of pipe.I absolutely LOVE the Laguna Dust Collection. Almost zero sawdust gets inside the cabinet or falls out onto the base. I still can't believe it. I've cut a few hundred feet of board and there is less than a teaspoon of sawdust inside the lower cabinet, and about a pinch of dust inside the upper cabinet. 99.99% of all dust gets captured through the dust port. Why other Bandsaw manufacturers have not copied their design, I will never know. Even bandsaw brands that use a tow-port design still have horrible dust collection. It makes no sense.Anyway, if you’re looking for a dust port reducer, this is the one. It’s very solid and thick enough that I would consider it to be heavy duty. Delivery was pretty good. No complaints.

This dust hood from POWERTEC connects easily with a coupler and reducer to your existing dust extractor setup. I purchased two of these, one for my miter saw and one for my table saw. They work great, but this thing really needs more of a flange around the outside to anchor it. If you're not right on the money with your cut, you're going to be repairing at the same time you're installing which is no fun. It worked for what I needed it for, but it wasn't the prettiest install.
