Try this: take a piece of pipe and an old fitting. Using
large pipe wrenches, tighten the two together until something
breaks. You will find that this is not easy to do, if you can
do it at all. It is easier with the smaller sizes of course,
but still not too easy. Point is, it is VERY HARD to
overtighten a fitting. The major problem is getting the
fitting oriented correctly.

Having run miles of threaded pipe in my lifetime, I tighten
the hell out of everything and rarely have leaks. You can
test with the gas pressure itself. It is better to use an air
test, but there are a lot of things to do to perform an air
pressure test correctly.


But then again, it's required for the inspection where I live.

Yes, if it is being inspected it must be air tested. But in
that case, the inspector will also require a licensed
installer. This guy is doing this himself.


I did it myself, and the inspector didn't have any problems
with it. In fact, he was my best source of info on how to
do it and how to test it properly.
