Infinity Tools 3" to 2" Reducer

Fits snugly and doesn't wobble like some of the universal adapters I've tried. The 3-inch end locks onto my dust collector hose securely.

Was tired of taping two hoses together every time I switched to the smaller port on my sander, and this reducer just solved it. The 3" end fits snug on my main hose and the 2" side slides right into the sander line with no adapter stacking. It's a simple part, but it works.

Snapped this onto my 3" hose and dropped down to the 2" line going to my benchtop sander without any tape or fiddling. The fit is snug on both ends and it hasn't popped off once during a long routing session.
