Strange, as the thread is not part of the water seal on a tap connector.
If you put it on the washer, I might understand it.


Putting it on the thread may lubricate it enough such that it will do up
that bit tighter with the same amount of torque.


Hmmm goes off to remove bath panel to check Nope, still drip free.
Maybe you're right, and its the re-tightening that's cured the problem?

So what is "Threadseal", "Sealing compound for watertight and gas tight
thread connections" for?, is this type of product (PTFE tape, included)
just for compression fittings? Do the flexible, braided tap connectors
rely soley on the fibre/rubber washer?
