Not for connecting shop vacs [Posted on 2007-12-31]
I purchased this with a dust collection hood for my planer. The hood has a 4" port. I thought that I could plug my shop vac hose into this adapter and then plug the adapter into the hood. My mistake! This will allow you to adapt a 4" hose to a 2.5" hose, but I had to tape the adapter to the hood as both ends of the adapter are female.

Make sure this is what you want [Posted on 2008-01-02]
This item works as advertised. I bought this when I was setting up my dust collection system and wanted to connect it to my spindle sander (which takes a shop-vac type of connector). I was not careful when I read the dimensions of this reducer. This will not work for such purpose. It will work if you want to connect your shop-vac to it and then connect the other end to the 4" connector of a machine. The problem is that a shop-vac is 2 1/4" and not 2 1/2. There is a different adaptor you could use for that.

waist of money [Posted on 2008-01-12]
you would think this fitting is all you need to be able to use a shop vac,
it wont work; unless you also buy a 4" hose and other fittings?
dont waist your money, (there are other fitting out there)

Did not fit correctly. [Posted on 2008-03-31]
I bought this adapter to reduce the 4 inch opening on my delta planner but it is the exact size as the opening on the planner. I though the purpose of a reducer was to fit 4 inch openings without another adapter. I had to buy a 4 inch to 4 inch coupling to make this work.

Decent reducer [Posted on 2008-04-26]
I use this almost daily when I swap the dust collector hood next to my lathe for a hose fitting to vacuum up all the chips that went elsewhere. I have a quick connect fitting on the 4" hose to easily swap it from the hood to this reducer. This reducer is such a tight fit that I can barely get it deep enough in the mating fitting to hold. It pops out easily just on the weight of 6' of 2 1/2 in hose.
