By using a PTFE tape sealant with a minimum thickness of 2.5 mil. you ensure that the tape is thick enough to provide a good seal and you won’t waste tape. To ensure a good seal, wrap the tape in the direction of the threads. You only need to use 2-3 wraps of tape, however thinner tape may need 4-5 wraps.
If it leaks, you didn’t put enough tape on (Teflon tape should make it watertight while being just hand-snug). Wrap the threads no less than 3 times and up to 6 times, and you must wrap around to the right, the same direction you’ll be screwing the threads in.
Beside this, How many times should you wrap threads with Teflon tape?
