Infinity Tools 4" to 2" Reducer

The 2-inch side fits snugly into my smaller dust port, and the reducer’s clean taper keeps airflow strong without any whistling noise.

The 4-inch end popped right into my blast gate with a satisfying click, and the fit on the 2-inch side is snug enough to prevent any leaks. I’ve been using it with my router table dust collection, and it works perfectly without any adapters.

My table saw's 4" dust hose connects to the 2" port on my miter saw now without any wobble or gaps. The 4" side seating inside the blast gate is a nice touch, and the reducer feels solid enough that I don't worry about it cracking under shop use.
