You have to have a thread on the metal pipe to make any kind of permanent connection. : : I am trying to join outdoor metal pipe to a plastic connection.The end of the metal pipe has been cut off & has no threads.When i : add a connection to the end of the pipe i still get a leak.I have put pipe goop & other glues but still get this slight leak.Is there a solution or do i have to rethread?Any help is appreciated. : thanks,gary.
