Looking through some web pictures, I ran across this picture, hope the owner doesn’t mind my using his picture as another example of the Rochester “B” plague.
I brought my feelings about this up to Jon a couple of weeks ago, that I felt that this enlarging of the 1/8” npt inlet was probably fairly common. Here you can see the forensic evidence of another over sized thread and the fitting having been screwed in all the way and still leaking.
