VARMHUS Stainless Steel 304 NPT Female Thread Pipe Fitting Adapter,3 Way T Shaped Equal Tee Connector Coupling (1/2")

Material seems OK, but thread depth isn't quite right. An ok value, but only because you can't get these locally

I bought 4 of these for a hydraulic lift. All 3 points leaked on the 4 I used. Ended up going to Ace hardware to get Ts that worked. Cost me several hours by the time I tried once again to reseal.
