1/2" PVC-Lock x 1/2" FPT 三通 33772

Swapped out an old glued tee on the main line and the stainless steel teeth bit into the pipe instantly, zero leaks even with the pressure on. Being able to rotate the fitting after tightening is a real lifesaver when you're working in tight valve boxes.

The stainless steel teeth really bite into the pipe, and that rotatable O-ring seal made lining up the thread angle a breeze. I’ve had it under constant pressure for three weeks with zero drips, and it’s far easier to work with than standard glued fittings.

Finally got around to swapping out a leaky old tee in my sprinkler line, and this PVC-Lock fitting made the job so much easier. The stainless steel teeth grip really does hold tight, and that rotatable O-ring seal is a clever touch.
