4 英吋 D型凸輪與凹槽接頭 x 內螺紋NPT | U-Tite | 鋁

Popped this on my water line for a quick hookup and the aluminum construction feels solid and lightweight at the same time. The hand-tightening connection was smooth, no tools needed, and it sealed up without leaking on the first try. Exactly what you want from a camlock coupler.

The aluminum feels solid but lightweight, so it's easy to handle even when connecting 4-inch lines. I’ve got it on a water transfer setup, and the female NPT threads sealed up perfectly with a bit of tape.

Fits perfectly on my 4-inch pipe and the thread cut is clean, so it spun on without any wrestling. The aluminum feels solid enough for regular use, and the hand-tight connection locked down in seconds.
