Infinity Tools 4" Thread Blast Gate

The left-handed threading took a second to get used to, but once I twisted it on to my Y-fitting it locked in place securely. The 4" hose threads onto the other side without any wobble, making dust collection much more straightforward.

The left-hand threads threw me for a second, but once I figured that out it seated perfectly against the fitting with no leaks. Switching between my table saw and planer takes about five seconds now instead of wrestling with a loose hose clamp.

Snapped right onto my 115-344 T-fitting and the 4" hose threaded on without any wobble, which is exactly what I needed at the end of the run. The left-hand threads threw me for a second, but once I stopped fighting them it sealed up tight with no leaks.
