Hi,
A while ago I purchased a Moen 3510 shower valve which has 'IPS' female connector, at the time I did not know the difference between IPS(straight) and NPT(tapered), and thought I could avoid soldering with that connector. Then I found Pex adaptor I purchased and all I could find on internet are NPT ones. So it will be returned. Before that I tried to screw the connector in and see it will only go about half way in.
To compare I took out the drop ear elbow and a NPT nipple (for hand held shower head). They are both NPT so I expect the nipple should go in more than half way. To my surprise, it also only went half way.
In both case, I didn't use any tool, just by hand, but I'd expect with a tool I might get a full turn in both case. Still I expect the NPT to NPT would fit better than MNPT to FIPS?
Am I missing something?
Here is a picture of nipple to drop ear elbow:
Thank you!
