Easily attach your 2-1/2'' dust hose to your shop vacuum with this swiveling hose adapter. With a 2-1/2'' hose, you can easily connect to standard dust collection ports of the same size, such as router table dust ports. The two ends of the adapter independently rotate 360°, helping to avoid kinked and coiled hoses as you move about the shop. Just plug the narrow end of the adapter into your shop vacuum and connect the wide end to your 2-1/2'' hose with our Bridge Hose Clamps (sold separately).

No more twisted hoses!
The flexibility of this swivel adapter takes away that annoying 'memory' that most dust hoses have. The adapter does the work of unraveling the hose, allowing it to lay nicely, instead of twisting wildly.

Good adapter for Bosch 4100 and Dust Rights
This is exactly what I needed to hook my Bosch 4100 portable saw to my Rockler Dust Right 2.5" to 4" tool port.

Attaching the 2.5" tool port to the saw itself was a super tight fit and disallowed the stand to collapse properly. This required me to adjust the the clamps and remove the tool port each time I broke the saw down. Adding this swivel to my Rockler 2.5" tool port let's me keep things connected and speedy, just like the tool ports were designed.

Practical
The swiveling part is great, as the hoses do not kink, but it also has a longer nozzle which help connect to the shop vac. I can see several applications for this adapter.

Using a 2 1/2" wand on shop vac is awkward. I hope this makes the wand and hose more flexible, free from the rigid connection at the vacuum.

Rayne on Dec 9, 2017
My current Dayton Vac hose only swivels on one end, and makes using the hose for bench cleanup a hassle, as I have to twist and turn the nozzle to access a lot of hard to reach areas. I went looking for a hose with swivels on both ends. These will make a hose with that desired feature.

greg b on Sep 6, 2015
BEST ANSWER: The smaller part fits my shop vac fine it is 2 1/2 " diameter. I like it because no matter how the hose maybe twisted it turns with it.
Does anyone know what the ID is of the narrow end? Thanks.
Kevin on Jan 21, 2017
BEST ANSWER: OD of small end is 2-1/4".
ID of small end is 2-1/8"
Why doesn't this fit my Shop Vac hose which is 2.1" ID, 2.28" OD. The hose fits into the elbow just fine and the elbow fits into the Shop Vac tubes just fine, but the large end of the swivel is 2.5" and fits with nothing I have. Now what do I also need to buy to make this work? Why was it not included? It looks like I some kind of 2.28" to 2.5" adapter ring or am I just suppose to use duct tape?
GEORGE L on Jul 29, 2016
BEST ANSWER: This product is for 2.5" hose. The larger end is attached to the hose and the smaller end is 2-1/4". This size fits most shop vacuum ports
