What is the difference between plumbers tape and Teflon tape?

PTFE tape helps produce watertight seals and bind parts together, but it will not effectively fix a cracked or damaged pipe. Plumber's tape does not have the ability to glue effectively around leaking pipes and most repairs carried out with it are temporary at best.

An important thing to remember is that PTFE tape should not be used when connecting PVC fittings or valves with a female (FPT) thread. If the tape is used on female connections, a wedging action can occur which will cause major stress on the joint during assembly. PTFE tape does not guarantee a leak free connection.
