2. Thread seal tape - Wikipedia

   en.wikipedia.org/wiki/Thread_seal_tape

   Thread seal tape is wrapped around the threads, lubricating the connection and allowing the two pieces to be screwed deeper together. Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths ...

3. Thread-locking fluid - Wikipedia
