Miles F. ★★★★★ Oct 22, 2026

The 4" side slides right into my blast gate without any wobble—that 3-15/16" OD measurement is spot on. Swapping between my big hose and the 2" line takes seconds now. Exactly what I needed to clean up my dust collection setup.

Finally got tired of taping adapters together. The 4-inch side locks nicely into my blast gate, and the 2-inch end fits my smaller hoses without any wobble. Solid dust collection for under five bucks.

Miles J. ★★★★★ Oct 20, 2026

The 2-inch end fits my smaller hose perfectly without any wobble, and the 4-inch side slides snugly into the blast gate port I already had. This reducer just works—no wiggling or leaks when the dust collector is running full tilt.
