I bought 3 of these 1" MNPT nipples. All 3 leaked when installed (both ends). I checked the thread pitch and it turned out that the thread pitch was 11 and is not 11.5 It's frustrating having to re-install everything twice and with limited space Now that the various hardware is in place the system is finally fixed.
