Infinity Tools 4" x 2-1/2" acoplamento rápido

Finally, a coupler that actually stays put on my 2.5” hose—the right-hand threads grip firmly without any wobble. The tapered quick-disconnect end makes swapping between tools effortless, and the fit is snug enough to prevent dust leaks at the connection.

Snapped this onto my 2-1/2" hose and it locked into the 4" port with zero wobble, no tape needed. The tapered end seats tight enough that I'm not losing suction at the connection anymore. Just double-check your hose threads before ordering.

I was worried about the threading since my old coupler was left-hand, but this one screwed right onto my 2-1/2" hose without a fight. The 4" tapered end clicks into my quick-disconnect nice and snug, no wobble or leaks so far. Fit and finish feel solid for the price.
