I use these when reducing the bathroom vent fan duct opening sizes. Works great, fits perfect on most fans.

I’m using this as part of a dust collection setup on a thickness planer. I have AC ducting running from the dust port and use this to connect to my dust collection bag. For this setup the collar of this reducer was maybe a little shorter than I would have liked but I got it to connect just fine with some big hose clamps. Price is great for what I was using it for.

This was the cheapest reducer i could find. Inflation is out of control. This thing should cost $2. It was almost 4x that much!Anyway, Its perfectly fine quality wise but it is not a snug fit to the AC Infinity T6 inline fan unit. There is an almost 1/4 inch gap all the way around. Was expecting it to fit tight. It doesn't. Should it stop you from getting it? No. Fix below.I was able to remedy this by adding some 1/2 foam door insulation (find it by the screen doors). Has sticky on one side and i just lined the inside of the reducer's edge (on the 6" side) and it fit like a glove. Didn't even need the foil tape because it was sealed. The 4" side worked fine with the 4" ducting I got here. Added some foil tape and I am good to go!

Actually measurements for the 4" end is OD 4-9/16" or 115mm which means it doesn't fit the 4" vent tube.
