In Europe flax or hemp fiber with a special grease/paste is often used for threaded fittings. The fibers expand when they touch water, creating a leak proof joint and the grease/paste helps lubricate the joint during assembly or disassembly as well as preventing corrosion/scale.
I have found that I can’t just back it to where I want it or it will be really loose, I have tried just tightening it more to the spot I want it but it can sometimes get too tight so I recommend you take it off and start over.
Sometimes there is more thread available at the other end of the nipple, so you could try taking the wrench off of the nipple and seeing if you can get the whole assembly to turn into the desired position. This of course assumes the other end of the nipple isn’t on a fitting where the fitting will rotate (although a straight coupling is ok to rotate).

Very easy when you have new and clean threads to work with. Im working on getting a used 2" NPT pipe tap too.
If you are just cleaning up existing threads you can take a 2" NPT nipple and cut grooves into it to remove rust or scale.

I saw a video about that process, I think Europe uses straight threads for galvanized pipe so that would help with the threads not being as tight.
@@jacksplumbingvideos7147 That's correct, Europe does indeed use straight threads for many things.
What if you tighten past the direction you want to go? Can you back it off or do you have to go another full turn?

Loctite 55 is a string used instead of tape and it lets you make small adjustments backwards without needing to start all over.
