    Like I said, I have always been a little perplexed about different threads. Frank gave a good image to look at and for some reason it tickled me enough to go out to the garage and pull out my micrometer.  64 years old and 1st time I was ever shown told the threads on iron pipe got bigger. I’m sure I read it, but didn’t absorb it. Measured the threads. ~1\2″ at the top and ~9|16 at the bottom.

    I get it now…

    Thx
