dust collection question "HELP"

[Jasun Brown]

I recently purchased a used Jet planer that has a 5" DC port out the top. My DC unit is a 4". No problem, I purchased a delta made 5"-4" reducer from an online store.. I was so happy to get to use my new planer.
Problem!!! Their advertised 5" is really only 4 1/2" ID and my port on the planer is a true 5" (4 15/16) or close. I don't have any local resources to purchase from so online is the only option. I don't want to keep "throwing it at the wall and hope for a fit"!!
Does anyone know of a 5"-4" reducer that is really 5". I am hoping for plastic but am open.
Thanks in advance for your looking and help!!

Another way you can go is to buy some 4" pvc S&D pipe and cut pieces from it, slit the side and snap the resulting collar around your adapter. Fill in the small gaps with other small pieces cut from the pipe. 2-3 collars made this way should get you to the right size. They can be made a solid assembly with a bit of pvc cement.

Your reducer *is* 5", on the outside. You need a piece of 5" hose between it and the planer.

If you have a heat gun, you may be able to heat up the plastic and stretch it over the dust port. Place tin foil on the outside and to block the 4" opening, place wet rags in the part you do not want to stretch, place foil on top of the wet rags to minimize the heat getting thru. Use the heat gun and heat the plastic evenly.
I am not sure if you can stretch it that far, but worth a try.

On my Delta 380, I used a piece of roll flashing and two hose clamps (4-6") from Lowes to make transition. Wrapped it around the outside of both pieces, and clamped it down. Here HD sells a lot of different sized reducing couplings (galvanized steel). You might want to check HD out.

Jason, go to your local Borg or HVAC supplier and purchase a 4" to 5" HVAC pipe fitting.

They come in two styles, reducers and enlargers, measure them to see which one fits your application.
