This allows me to use a Ridgid Shop Vac WD970, a 9 gallon with 1 1/2" ID hose end, to the 2 1/4" ID Dewalt DW745 exhaust. The product says 2-1/2", but it has an OD of 2-1/4" and fits inside the DW745 exhaust. It fits snug to the Dewalt, but is a bit loose on the Shop vac but suction keeps it on while in use. Neither Ridgid nor Dewalt customer support knew about this item. Ridgid told me to buy a 2-1/2" new hose (cost $20). This saved me $15. Good buy. Hardware stores probably have it, along with entertaining employees. If you don't need that, buy from Amazon and get free shipping.

This attaches a 1.5" hose to a 2.5" inch attachment or dust-port. Since the hose fits inside the attachment, this will not allow you to attach a 2.5" hose to a 1.5" attachment or dust port. For example, this will not attach a shop-vac hose to a machine with a 1.5" dust port.

I have a Craftsmsn router table with a standard 2 1/2" dust port and a Shop Vac with the smaller 1 1/2" hose. This fits the dust port perfectly, but is sloppy on the shop vac hose. It still works good though.

I don't really understand making vacuum fittings that aren't at least somewhat rubberized. This is pretty rigid plastic, so whatever you're attaching it to must be exactly the right size.

Just so you know, the listed dimensions are OD, so don't try to use this to attach a regular shop vac style hose to a handheld powertool.

What it's great for is hooking up a 35mm hose to a Makita random orbital sander.

I needed to connect my Harbor Freight wet/dry vac to my Porter Cable TS270 table saw dust port. It almost didn't fit. The 2.5 inch end fit inside of the dust port after forcing it in as hard as I could - I'll be leaving that permanently in there so I don[t have to do it again. A bit of sanding would've helped too. The small end didn't fit directly on my hose end, but it did fit onto one of the rigid foot-long hose extensions that came with the bacuum. They should be the same size as the vacuum end but apparently they were just a tiny bit smaller... small enough to barely fit into this with force.

So, I have a long, hard plastic tube sticking out of the back of my table saw. Without the vac attached it is like a sawdust gun.

At least I don't have to use duct tape.

2.5" Universal Tool hookup to 1.75" hose - bought this to fit my Black-Friday special ShopVac (cheapo version) 1.75" hose to connect to my Dewalt DW745, Bosch RA1181, and later my Delta 36-725. Works, but I'd visit the store to check sizing. My empty 1.75" hose end was about 2mm too lose, and I have to duct tape it when I collect dust. The 2.5" end fits every tool's 2.5" port that I own.

Neither end measures as described. I've had this problem with many vacuum attachments. I am no longer going to buy any vacuum accessories on-line. I have a Ridgid 14 gal shop vac with 2-1/2" hose accessories. The fitted ends of my hose are 2-1/4". But even 1-1/2" end measurements are not right. The 1-1/2" end does not measure 1-1/2 inches either inside or outside. Now its just garbage to me.

This little unit is perfect for adapting the 2 1/2" outlet of my JET 12" Disc sander to the 1 1/2" hose of my ShopVac....which means you dont have to fit a filter to the unit as long as you are running your ShopVac. It's inexpensive, relatively unobtrusive and robustly constructed.
