    Looking for dust fitting adapter with 2-1/4" OD on each end.

    I am Looking for dust fitting adapter with 2-1/4" OD on each end. Preferably slightly tapered.

    I need to attach a hose with 2/14" ID end to the inlet of a Shop vac which has a 2-1/4" ID and accepts a 2-1/4" Hose.

    Right now I have a shop vac standard 2-1/2" hose which has 2-1/4" OD fittings (that mate with the shop vac inlet and various suction tools) molded to each end but I want to get that 8 foot long piece out of there.


    Can't seem to find one anywhere.
    I can find these which is it except for the opposite sex, so to speak:

    Any ideas on how to make one quickly with some tubing that is 2.25" OD? WHat tubing is that? PVC is not close enough.

    If your only tool is a hammer, you tend to treat all problems as if they were nails.

    Muffler pipe adapters.
    Some of the popular chain auto parts stores sell a variety of adapters for numerous size pipes that can be used for dust collectors and vac systems.

      It's not tapered, but you can get short lengths of Pet G from Mcmaster Carr that size.

        There is a sketch! Did you just add it? It wasn't showing up at all on my iPad yesterday.

            Yeah, I added it a couple of hours later... had it but got distracted on the way to the scanner computer. Hehe.

              I've just used a very short hose (e.g. a couple of inches) for that scenario. You can get the male fittings to make the hose.

                I went by the hardware store and found that 1.5" PVC pipe uses couplings that have a 2.22" outer diameter.
                The hose inlets on the vac and hose end were very close to 2.29"
                So I wrapped about 3 layers of 3/4" masking tape around the middle of the coupling to build it up by 16-32 mils... ( 4 mils thick and 4 layers on each side) Thicker in the middle, outer part with none, to make a taper.
                Then I used some 2" wide duct tape which was about 6 mils thick. I left about .2" at the ends bare and worked to the middle where it overlapped about 3 layers.
                When done I had 2.23" OD near the ends and 2.31" diameter (OD) near the middle. .Glad to say it worked like a champ, the taper was perfect, and total out of pocket cost was $1.29 plus tax.

                  Nice. You could also heat it up and stretch it out.
