4" PVC Pipe to 4" Dust Collection Hose No-picture-s No-picture-s Click the pictures to enlarge them

I made my own inexpensive dust collection system using 4” PVC sewer pipe and fittings from Lowe’s. The parts were a fraction of the cost of true dust collection ducting and fittings. The one issue I had was that the diameter of the sewer pipe I used was too narrow to get a nice fit for the flexible drop down dust hose. To solve the problem, I invested in Dust Right transitions and they fit perfectly. Although pricey at $15 each, I thought they were money well spent.

You can also heat schedule 40 PVC with a heat gun to soften it and push a dust fitting into it to make a snug fit. There’s a youtube video on home made cyclone separators that shows how to do it but I don’t have the link.

I used coupling found at Lowes for my simple PVC system. Like your set up better!

And why does 6” pvc pipe cost $42 / 10-ft while 4” costs$ 12 / 10-ft? It’s only 50% more material at 3x the price.

Still, I’ve been fixin’ to upgrade my DC and the fittings are the thing that run the price up.

That 6” pipe is has straight ends, and a 6” coupler is another $12.

Look for a local HVAC supplier. They’ll most likely will have 26ga or better piping and fittings at a better price than PVC. I just posed a source for Central Florida as they were FAR cheaper than PVC.

You can get a Sch40 to S&D adapter for about $2.00, a stub of S&D and you’ve got it… Or just run 4” S&D if you are using 4” at all. It’s less expensive, and fits the hose just fine.

I used to work in plastics and also the industrial heater industry that supplied the heaters to the extruders of pipe.
The big cost difference is in three areas – bigger molds and larger extruders, LOTS more storage, and the cost of shipment, since you cannot get anywhere near the footage of 6” pipe on a truck that you can with 4”. Oh, and QC – lots harder to fill and extrude 6” since there is a lot more wall thickness to keep filled, so it comes out slower.

Well, that explains it! :-)

I can’t seem to find the S&D listed online at HD or Lowes. I just need to go into the stores and look. It’s the Sch40, that’s $42 / 10 ft.

On another thread, there was a sheet metal guy who said you can make your own metal fittings – even Y’s and elbows more easily than you think. So… I’ve ordered a 1922 book on sheet metal “development” as they call it. I’ve got tin snips and gloves. It’s worth a try. Maybe I’ll end up with metal ducts after all.

I’ve seen the youtoob video of making reducers yourself out of straight PVC pipe with a heat gun and some shop-made dies. That seems worth doing too – and a lot easier than making reducers out of sheet metal, no matter how good the book might be.

Apologies to the original poster – who was reviewing Rockler’s fittings.

+1 that’s what I did. Its not a perfect fit like Rockler. But it works just fine. 4” house fits on the 3” side of the reducer and just use a normal hose clamp.
