Tools and Hardware Reviews of Jet JW1044 4-to-2-1/2-Inch Reducer
Customer Review: Is this really what you need?
Summary: 2 Stars
I bought this to connect my 4" Jet hose to the 2 1/2 port on my bandsaw and table saw. All the current research is to keep the dust collector draw (I have the Jet 1100) at 4" (6" on a planer) until right before the machine (actually to rebuild any machine to accept a 4"). The ad does say it's 2 1/2 OD and silly me, I didn't bother measuring the 2 1/2 at the tool end. Guess what? They're both 2 1/2 OD so they do NOT fit together. In my opinion, this is a worthless adapter - as it doesn't advertise as a hose to hose connector, and hooking a 2 1/2 shop vac to a 4" opening at the tool is like trying to suck dust out of a garbage can with a straw - the physics are wrong - this should be only used for reducing a 4" hose to 2 1/2" at the tool, but again it's the wrong diameter. A proper adapter should be either 2 1/4 OD or 2 1/2 ID to fit over the tool's port. Does anyone know where to find such an animal? I finally found a rubber plumbing connector (at Home Depot) that joined the two 2 1/2 OD fittings together. This works but we should've have to do this for a peice of plastic they charge over $5 for. Please do not hook a shop vac to a jointer and expect to remove the 1 to 5 micron diameter dust particles that can cause COPD (lung disease), you'll only get the chips, sort of.Customer Review: It Won't Do That

I bought the adapter because I want to use my shop vac with my new Delta table saw which has a 4" dust collection port. It won't do that--it is the same diameter on the big end as the dust port on my Delta (or any other piece of equipment). I had expected that it would fit INTO the dust collection port and then I could hook up my shop vac. It won't do that, so I am still looking for one that will. If you are connecting hose to hose it should be fine, but I gave it the 1 star so you would notice the issue I raised.Customer Review: It does not fit unless

You need a a piece of hose between the adapter and jointer since they both have the same OD. It is kind of anoying. It should have come with a piece of hose as well.Customer Review: It is what it is.

After purchasing the adapter, I found that it does not fit on the dust shield of my Jet Table Saw without a piece of 4" hose between the adapter and shield. After installing the hose, the adapter works fine.Customer Review: Item is not as shown in the pictures

The picture seems to show an adapter with a tapered transition from the large to the small dimension. In fact they have a 90 degree step making them not suitable if you are using a shop vac on the small end to exhaust a tool with a large diameter output. If you want to connect a smaller vac hose to a large dimension shop system they would be OK. I just threw them away.
