Question Best way to connect threaded copper pipes?

I have a problem connecting threaded copper pipes - I get really small leaks. I teflon tape them, and plumbers goop (the toxic mustard colored stuff). I don't know if I tightened them enough though. Any suggestions?

Threaded copper fittings can be sealed by wrapping 2-3 flat wraps of teflon tape clockwise only as the male threaded end faces you (or use pipe compound), and tightening it tightly.
Don't solder near them after you make them up.
Good Luck!

I soldered that joint. It was a copper 90 to threaded and I had to thread it. Oh well, I'll just need to fix it...

Thanx again...

With Mike here :Anytime you have to put adapters like CxM, CxF and the drop ear 90o L's you solder them on to the copper line first. Then dope and put the pipe in.
