Can you use Teflon tape on a hot water heater?
Use Teflon tape (but not pipe dope) on the male threads entering flex-connectors. If your water heater has female-threaded tapping, you’ll need a pair of short 3/4 inch nipples to accept the flex-connectors at the bottom. If the heater comes with 3/4-inch male-threaded stubs, the nipples are not needed.
When should you not use Teflon tape?
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.
What is the max temp for Teflon tape?
PTFE is completely stable up to +260˚C (500˚F). Decomposition is slow up to 400°C (750°F).
Does Teflon tape stop leaks?
Teflon tape will help prevent plumbing leaks. Teflon tape is an absolute essential for most plumbing projects. Its physical composition allows it to fill pipe threads and fitting threads with a sealant that will prevent water from leaking through the thread connection.

How many times do you wrap threads with Teflon tape?
You always want to wrap seal tape around threaded pipe fitting in a clockwise direction. In most cases for a new joint you should apply only two or three wraps of tape.
