Infinity Tools 2-1/4" x 2-1/2" Quick Coupler

It adapts a 2-1/2" hose to a 2-1/4" O.D. fitting, so you can connect a 2-1/2" dust hose to a 2-1/4" outer-diameter port.

The threads are left-handed to match the winding of most dust collection hoses, so the hose tightens as it's threaded on instead of loosening.

It's designed for the thread-on connection of most standard 2-1/2" dust collection hoses, whose winding matches the left-hand threads. Browse compatible dust collection hoses.
