【How-to】How do you seal a leaking thread

You can use different kinds of tape to solve different plumbing leak problems. Use pipe thread tape, sometimes called “Teflon” or “Plumber’s” pipe, to fix leaking pipe joints. Use silicone, sometimes called “self-amalgamating,” “self-fusing,” or “leak repair” tape, to fix hairline breaks or other non-joint pipe leaks.
