Very basic question on galvanized couplings

I need to replace a few sections of old 1/2 galva piping. How do I achieve the exact desired orientation after a combination of nipples/elbows? In other words, is it OK to undertighten the elbow connection if necessary (it could be almost a full turn in the worst case!)? Or is there some other trick of the trade?

Sorry to ask something so basic but I can't find the answer anywhere.

Thanks.

try wrapping threads with teflon tape. I have done this to save a round or two on a nipple

Thanks for your reply. I certainly was going to use Teflon tape but was not sure if this was sufficient.

You'll also want to use thread sealant. Rectorseal is the best brand to use.
