Decent reducer

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.

Did not fit correctly.

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.

waist of money

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)

Make sure this is what you want

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.

Not for connecting shop vacs

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.

Ideal for woodworkers with Shop-Vacs or the equivalent, the Jet 4-Inch to 2-1/2-Inch Reducer allows you to step down from a larger size machine. The reducer connects 4-inch line to 2-1/2-inch dust ports. The step down increases air velocity where it is needed most. With an outer diameter of 2-1/2-by-4-inches, this reducer lets you adapt to many machines.

the 4 inch to 2-1/2 in reducer is useless with the Jet saw I ordered. The 4 inch end is exactly the size of the opening of the dust collector in the saw, so it neither goes into nor around the opening. The 2-1/2 inch end fits into the dust collector hose perfectly. I rated this one star because 0 was not available

Jet 4 inch to 2 1/2 inch reducer for dust port

This reducer did fit my Jet band saw because it has a 4 inch cast iron port. I also ordered the 4 inch quick disconnect so I used a pc of 4 inch pvc to connect the 2 items and they work fine.

So we used this reducer to fit a hose through the 2-1/2 inch part to release the hot air made from the air-condtioner even though we had to use a lot of duct tape. It works but I guess that the hose was too long and it blew a fuse. Overall this item was shipped as described!

A basic plastic 4" to 2.5" dust collection system reducer. Quality but nothing magic.
