Review on 💧 SZZIJIA 1/2" AC 110V Automatic Timed Water Tank Drain Valve with 2-Way Direct-Acting Function - US Plug by Tyrone Lee

I use this valve to drain my compressor tank every few minutes and I love this valve. I don't like threaded connections. I bought a valve with 1/4" ports and assumed it was 1/4" NPT. You are not. These are 14 TPI threads, which is the same thread pitch as NPT, but these threads are DIN straight, NOT tapered, so a rubber o-ring or gasket is required to properly seal the fittings . A gasket is included but I had to purchase an O-ring to seal the other joint. The connection is good. It's just a straight DIN threaded connection for Europe/Asia instead of the US/UK NPT connection I was expecting. I would give 5 stars if the manufacturer supplied or offered NPT tapered thread fittings.
