NOT npt. See review.
Please learn the meaning of National Pipe Taper and NPS and why would you offer it as NPT when it's NPT on the female side and NPS on the male side? Straight thread is not going to fit Into a NPTF fitting. It will always leak and will not seat. Your Fittings are a odd thread, they will fit together to themselves in both configurations, but not to American piping,. So I assume not only is the male side NPS but also a ridiculous metric sizing not compatible with any American standard.

Little stiff
Using these in a water filter to keep water from going between the 3 filters, so the filters can be drained in the winter. With no pressure in the filter, the water will not drain. Ended up removing them

works as intended
no surprises with incorrect threads and works for what I have intended for it in a nice compact package(using it in a DIY vapor blaster setup)

Works but didn't last
Seemed to be decent at 1st but one broke on me. Guess we'll see if the 2nd holds up

Female to male
I looked all over and could only find valves that worked in the other direction. The wrong direction for my application. This valve has solved my problem!

Worked great
I replaced the original plastic cold water inlet to my RV with brass fittings after having a leak. The valve worked perfectly and I haven’t experienced any additional leaks.
