Infinity Tools 3"～2-1/2" レデューサー

Finally a reducer that doesn't act like a bottleneck—I hooked my 3-inch hose to the 2-1/2-inch one and the dust flow stayed steady, no clogging at the joint. The tapered shape makes the swap feel seamless, and it's rigid enough that I don't worry about it collapsing under vacuum. Exactly what my sho

The taper on this reducer is gradual enough that it doesn’t choke my table saw dust collection like a straight step-down adapter would. I just swapped it in and can already tell the chips are moving through the hose better than before.

I was worried about airflow loss going from 3" down to 2-1/2", but this tapered reducer keeps things moving smoothly with no noticeable restriction in my dust collection setup.
