Infinity Tools 4" Y-Fitting

The 45-degree inlet design really cleans up my dust collection layout, reducing sharp bends in the hose. It fits standard 4-inch pipes securely without any leaks. Glad I swapped out my old T-fitting for this.

Wasn't sure a 45° inlet would make much difference but my table saw run flows way better now. The fit over standard 4" hose is snug and it hasn't popped loose once during a long session.

Snapped this onto my 4" main run and the hose slid right on with no tape or fiddling. The 45° angle saved me from a sharp bend that was killing suction at my table saw. Solid fit, no leaks so far.
