Rockler 2-1/2'' to 2-1/4'' Conversion Port

Connect your shop vacuum to benchtop tools like a band saw or chop saw or anything with a 2-1/2" OD dust port! The 2-1/2" ID fitting with rubber boot and included hose clamp seals tight on 2-1/2" ports like T- or Y-fittings on your dust collection system or a power tool dust port. The other side, a 2-1/4" ID fitting, quick-connects to the hose on your shop vacuum, making it easy to bring dust collection to every benchtop tool in your shop!

have 3 now; fit is good to shop vac, no leaks
I have one for a shop vac to regular hose for the house, another for the wood shop to regular hose, and a third for the woodshop
dust separator bucket. The fit is just right with no apparent loss of suction.

Works great for what I purchased it for
Recently I built me a router table like the deluxe router station that Norm built on the New Yankee Work Shop and this was the last part needed to complete the vacuum hook-up and it work great to clamp to the 2" pvc.

Perfect Solution
The perfect solution for connecting 2-1/2" hose to a blast gate. Especially with an E-Z Squeeze clamp, on and off quickly without full and the swivel makes maneuvering the hose easy.

Perfect for my application!
I hunted for weeks for one of these! So glad I found it! It should be called a "2" PVC to 2-1/2" Shop Vac Adapter". I bought 2, one for the dust hood I built for my miter saw, and the other conveniently fit the exhaust port on my band saw! 2 Thumbs up!

Does this rotate/swivel or is it fixed?
Ron E on Apr 5, 2016
BEST ANSWER: I should add that although the hard plastic part can rotate withing the rubber sleeve, it doesn't move as freely as these two parts together: "Rockler 2-1/2'' Swivel Fitting for Shop Vacs" in "Rockler Dust Right® 2-1/2'' Rubber Union for Dust Collection."

Additionally, on occassion the plastic has come apart from the rubber when I had pulled the hose too hard. Easy to put back together, but if you want a more positive swivel connection, get the two parts.
will this work from a shopsmith vac to dewalt plainer?
roger on Oct 20, 2016
BEST ANSWER: Hi Roger,
I can tell you the measurements of this adapter, which worked great for my Craftsman Sanding Table, but you'll have to check the exact measurements of your planer port and vacuum hose to see if they will fit. The Conversion Port's rubber flange with the hose clamp has a 2 1/2" inside diameter, so you'd want a 2 1/2" O.D. outlet from your planer. The hard plastic end of the Rockler adapter (which nicely swivels freely, by the way) has a 2 1/4" I.D., so your vacuum hose end should be 2 1/4" O.D.
My shop vac hose was too narrow, so I used Rockler's 2 1/2" Dust Hose #56647 with a 2.5" coupling # 36973. I hope this helps !
I have a 2 1/2" OD port and a 2 1/2" hose. Will this work as a quick connect? I'd place the hose on it permanently and slip it on and off the port. I can't find a specific product that describes that situation.
Brian on Mar 22, 2017
BEST ANSWER: Hi Brian,
I struggled with this type of connection, too. The rubber part of this #49887 conversion port will be a loose fit over the outside of a 2 1/2" port, and it may be time consuming to change the clamp if you want to move it. I think you will want part #31660, 2 1/2" swivel fitting, which you can permanently clamp into both ends of your hose with hose clamps either #39482 or #29509. I found that these connectors on my hose will nicely slip into 2 1/4" I.D. fittings such as my shop vac intake and a 2 1/2" port or elbow from a stationary tool.
Hope this helps.
