Fitting A Valve To a towel warmer

Before fitting the valves to a towel warmer, I am having a look at this:

..........and note the the guy wraps the tape round the thread around 13-14 times. Is this normal practice and will such a precaution prevent leaks?

Ask 5 different plumbers how many wraps and I bet you get 5 different answers.

Personally ive taken to 5 wraps of medium density ptfe on threaded joints. And I woukd say that 13-14 wraps of any ptfe would make screwing the thread in uber difficult.

And wasteful, as the majority of it will be forced back out of the joint. As said 5 wraps of good tape is enough...........incoming.
