Moving Gas Line

I need to relocate a gas line to accomodate a new range. I'm going over to the right and down. The existing elbow is facing out towards the kitchen, I want it to face towards the right.
Is it O.K. to tighten this joint 90 degrees rather than disassembling everthing? Basically can old joints be tightened without fear of leaking?
Thanks, Brian

Nothing involving changes to gas piping can be done without a chance of a leak. If the pipefitter who originally installed this used a hard-setting joint compound it could very well leak when tightened another 90 degrees.

You need to be able to also "back up" the fittings and/or nipples with a second wrench to make sure that it doesn't turn in another fitting while working on the outermost fitting. This could involve opening the wall depending on how your piping is installed. At the very least you need to remove the elbow currently in place and clean all the old joint compound from the threads and apply new joint compound before making up the fitting in the direction desired. Be sure to use a joint compound that specifically states it is applicable to fuel gas usage.

And if you use Teflon tape instead of dope do not use white or pink. Use only yellow intended for gas use. It is thicker.

Question Gas Pipe

Have to say that any gas fitting thats been in for any length of time has to be removed and re-installed with new sealer.
