Hi all,
We have an older house, and replacing the range I found that the gas line kit I purchased is smaller than the existing connections. I think all I need is a coupling to make the transition, but I'm not sure how to measure what I've got to get the right remedy: inside the line? outside the threads? somewhere in between?
My second question is: is it OK to cover the existing flare with a F to F coupling in order to install the excess flow valve? It seems like more bits than strictly necessary, but I'd rather not disturb the existing parts more than I have to.
This is the new line I picked up:

The end that attaches to the range does appear to fit as intended, so it's just the wall side I'm dealing with.
Out of the wall, I have the gas line, the shut-off valve, a short length of pipe, then the flare.
Problem is, I'm not seeing F to F couplings that look like they would work. This appears too short:
As an alternate solution, I could cover the flare with another flare instead of an F to F coupling. It seems like 3/8" and 3/4" are the standards used, so if I buy one of each that reduces to a 1/2", one should work.

These can also arrive tomorrow, which is nice, because, you know, food.
Thanks in advance!

In particular the idea of going with a smaller gas line like you suggested was extremely situational. Most of the time you just could not do it, and if that meant all work stopped for the day until we got the right parts then that's what happened. I think there are times it can be ok, but I won't pretend to have the expertise to comment. I also wouldn't trust anything short of a licensed plumber to say it for sure, and that will mean an in person visit. Shrinking the pipe can affect how much gas is put out which does not end well. Gas is really, really dangerous stuff and when things go wrong they can go catastrophically wrong.
As for how to measure it, well I am honestly not certain. You just learn what the sizes are is the easiest way to put it. Match like to like and move on from there. It will get you the right size but is a pain in the ass if you haven't seen it a ton.
You'll need some form of sealant/pipe dope that's compatible with gas.
This is the only correct answer.
