Duct tape, wooden donuts, adapters (my last choice). You can also use HVAC and/or PVC fittings. The only hard/fast rule of DC ducting is that nothing fits….you have to improvise.

Harbor frieght has a good kit that goes with their DC. They give you lots of clamps.

I’m having difficulty getting the hose over the fittings. Any better way than brute force? soap, wax or hot water? Is there any easy way to shift hose from one tool to another? I don’t want to permantently secure to one amchine.

I have heard silicone spray lubricant is good for this purpose. I’m having the same problem with my new Harbor Freight 2HP dust collector, so I’ll test it out and get back to you.

Rockler has a hose system with a an expandable flex hose with a handle to move from machine to machine. Be careful, by the time you buy the hose and all the fittings it may be more cost effective to run lines to all your machines with blast gates.

I have the gate that ryanira posted on my dust collector although that wasn’t too necessary since the hose could just be muscled onto there but since I wanted a gate that seems like the best option. What I’ve posted sits at the other end of the hose and I believe is the solution you want. My hose required a ton of effort to get onto the tablesaw an I never managed to fit it on the dewalt planer. This attachment slips right inside and stays snug. Hasn’t dropped out of the table saw or slipped out of the planer yet.

If you are using PVC, you can use standard PVC couplers as a great quick disconnect system. The flex hose slips in on one end, and make your own port for your tool using PVC pipe, and the coupler slips right over that. Look toward the bottom of this article for pictures of this: https://www.wwgoa.com/articles/projects/-d-o-g-simple-approach-for-dust-collection-ducting/

I use these on several tools in my shop and they really work great. If the flex doesn’t fit tightly in the couple you could tape it in place, but I haven’t had any problems, especially with the 6” flex.

I have had the same issues and found a combination solution.
Using both the std 4” hose fittings and the 4” white sewer pipe fittings together with a liberal
amount of an inexpensive hardening caulk has done the job. Fitting the two systems together
takes some trial and error but if you can get them close, the caulking makes
the fit. The key is to find fittings from both systems that will fit into each other loosely.
Once assembled, caulked and cured you have what you need to join the two types of pipe.
I have used this successfully for my whole shop.

Hope this is of help. Cheers!

I have no idea why the male fittings for ductwork aren’t a uniform (and correct) size. I recently had a situation where the coupling was a struggle to put on or take off, but the el fitting was an easy slip on. From the same vendor. To make the coupling work reasonably well, I sanded one end to a smaller diameter by rotating against my 6 inch stationary belt sander. Worked okay. I only reduced one end, as the other could stay put.
For quick switch over from one machine to another, an annoyance is having to loosen and tighten hose clamps. I cut standard 4” hose clamps, and rivet the 2 parts of a draw latch onto the resulting ends. Now I can quickly and easily swap between machines. I leave the adjusting screw in place, so the clamp can be fine tuned to the variable diameter fittings. I’m even thinking of wiring the clamps onto the ends of duct hose that gets swapped pretty often, so they don’t drop off while the tension is released during transition.

It depends on the hose you buy and the fittings you use.

The real heavy duty grey hose won’t fit over Sewer and drain pipe but Woodstock makes a quick disconnect threaded blast gate that fits on your 4” dust port connections. You simply screw it into your hose and put a hose clamp on it. here is a pic.

There are also threaded quick disconnects that don’t have a blast gate.

If you have the clear hose and S&D pipe I’ve always been able to get it on the fittings without the aid of any soap….

i had the same problem recently getting someo flex of the 6 X (2) 4” adapter of my delta 50-850. i used a hair dryer to heat the flex adn it slipped onto the adapter quite easily. i used to use pots of hot water. the hair dryer is MUCH better. when i want to remove the flex from the adapter, i just heat it with the hair dryer and it slips off easily.

-- there's a solution to every problem.......you just have to be willing to find it.

I used to use the Rockler system mentioned upthread (It’s called Dust Right, here are some of the items ) before I had my permanent system put in. I connected my portable dust collector to the handle and put the ports on my tools. It worked well and it was easy to move from tool to tool. If you decide to go this route, I am no longer using the parts that I bought and could sell them to you for less than new cost. I have the handle, a handful of 4” ports and I think two 2.5” ports. Send me a message if you’re interested.

Have your say...
