Topic tags/keywords: dust collection fitting reducer vacuum

Does anyone know of a source for a 2-1/4” ID x 1-1/2” ID (OD’s don’t matter) dust collector/shop vacuum reducer/fitting?

This is to allow me to use my Oneida Dust Cobra (or really any vac system with a conventional 2-1/2” hose) with my smaller power tools – Porter Cable ROS, Dewalt router, Dewalt miter saw, Bosch jigsaw – all of which have a 1-1/2” OD dust port.

I suppose I could turn one out of some easily machined plastic or have a sheet metal contractor custom make one if I can’t find a source.

Any help would be great.

Thanks,

Alex

maybe something like this could work for you, just cut off the reducer to the size you need.

this is one of the best things i’ve gotten for joining disparate size hoses:

cstrang – A universal fitting like this one – only with another reducer on the big end, unfortunately – would work. It becomes very bulky and cumbersome, though, and for some tools (e.g., the router and jigsaw) it also becomes dangerous.

toolie – Unfortunately, your kit will not work either. This is also a prime example of manufacturers not listing what the dimensions refer to – ID? OD? Both?

Check with Amflex to see if they have the adaptor you’re looking for. I see they also make custom parts. Maybe they could make an adaptor for you.

Also, I’ve had good luck with Bosch adapters. Call Bosch CS and ask them for the I.D.s and O.D.s of their different adapters. There is also information about size and/or tool compatability in the Amazon customer reviews of each Bosch adapter.

Alex—Did you find the adapter you were looking for? I was home last week and I measured my various adapters. As close as I can measure it, the Bosch 2605702022 adapter has a 2-5/16” I.D. on the large end and a 1-9/16” I.D. on the small end. These dimensions may taper to a slightly smaller dimension on the inside. Also, the large end has a second ring on the inside which may or may not have to be removed for your application. Amazon sells it.

I’m in a similar boat in that I’m trying to hook up my DeWalt miter saw to a standard 2 1/2” dust hose. I’m going to try either this or this and I will let you know if either works!

That foam pipe insulation works well to ‘shim up’ a too small hose fitting.

Update – neither of those products I linked worked for my Dewalt, even though the set of three adapters worked on a Dewalt display model in Home Depot. It must not have been the exact same model.
