Mike,you putz!, copper threaded parts are best to be fitted with a
harder metal. I think that is where they used the galv?? I replace
the galv fittings with brass even if there is copper avaliable. A
copper threaded with copper ends up screwing the threads (both are
soft). Using brass or galv keeps the threads erect. when you thread
a male plastic fitting into the copper, the plastic ID is way small
and it is hard to back out. Working with old copper lines I fit a good
treaded pipe wrench close to the copper fitting to hold the stress
from twisting the old line (for every action there is a equal and
opposit reaction)
