Connecting small or unusual hose sizes to dust collector

[Ed in Tampa]

A few weeks ago people were talking about cobbling various adapters to fit dust collection to small tools. I wonder if this setup would work.

I bought something very similar a couple years ago, 20' Cen-Tec on Amazon, although it only has 2 adapters with it, looks like 1.1" and 1.35". The large end on the hose fits nicely in the DC3300, one of the adapters, the 1.1" I think, fits on my random orbit sander's exhaust port perfectly.

The inside of the adapters, maybe the outside as well but can't check at the moment, has a grippy material, maybe a little bit of ability to fit over something slightly over sized. The adapters snap together to the hose end securely and disconnect with little issue, I don't think they will easily come apart.

If anyone has any specific questions, I can look at my set this evening.

I see that I can now get a set of 5 adapters on Amazon, looks like the same sizes that are in the Infinity set, ordered and should be here tomorrow. Amazon has 10', 16', 20', and 30' hoses and the 5-piece set, https://smile.amazon.com/gp/product/B07 ... =UTF8&th=1. The only difference I can see is the ring color on the Infinity is silver vs blue on the Cen-Tec.

I did notice that set on the back of the latest catalog. I like a couple of the features over the set I have from Rockler. I got this set initially:

Then added these:

And later a second hose.

What think I like about this new system is the easy change system. On the rockler it a screw off and on which is not bad but never going to be as easy as the infinity version. I like how the demo shows someone stepping on the hose and it returning to round, one of my rockler hoses has an oval section where I guess I stepped on it????

Have not compared the hose end sizes but it is likely that these are all designed to fit the same tool size ports. It gets confusing as some go inside and others go over.

I believe I may have gotten mine in 2015 and they are still going strong due to the materials, this is an unknown on the infinity version.

I find that my dust collector flows a lot of air if I use the 4" or 2.5" hoses, but flows almost nothing if I choke it down to 1.25". My Shopvac does better with the 1.25' hose than my dust collector. It seems to me that the dust collector is high volume, low pressure while the Shopvac is high pressure, low volume.

You're exactly correct. My uses so far have been to attach to the ROS and also to do minor cleanup around my little CNC. Connected to the DC, it does the former well, the latter gets done eventually.
