Daox,

Don't feel bad . . . .

Teflon pipe tape works great if the threads are in good shape. More recently, the quality of metal pipe threading has gone to hell.

I never had leaks, in the past, but I get them regularly now if I just use teflon tape.

I still use teflon tape on the outside threads, but now always use pipe "dope" on the inside threads. A bit more time, but NO leaks.

Hope this helps.

Steve

ps pipe dope is messy and nasty . . .
