Common Size (but evidently custom?) Dust Collection Reducer

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

-- A hammer dangling from a wall will bang and sound like work when the wind blows the right way.

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.

Thanks, Lynden. I’ll give them a try.

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.

this is what i use and most box stores or plumbing suppliers carry them.

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.
