    Thanks Dereton. I always use Fernox jointing compound for compression fittings. I never find using PTFE tape never really effective on its own. An outside pipe, which is adjacent to my outside tape, was ‘weeping.’ I used PTFE tape, but it didn’t resolve the problem. However, after using jointing compound paste with PTFE tape, it did the trick.

      When I install radiators I usually do 23 to 25 wraps. If I do less, then the tail doesn't get tight by the time my spanner starts touching the rad.
      I have recently bought some loctite 577 to test out. I have had some success with loctite 55 as well.
      One day when I have the time I will probably do some sort of test to see what happens when I only do 6 or 7 wraps like some of the rad valve manufacturers say.

    Quick question, you say to use PTFE tape on all threads but on your how to remove a radiator for decorating there wasn't any PTFE tape shown when disconnecting the pipes from the radiator or when reconnecting the radiator.
    If there isn't any PTFE tape on the valve thread when I disconnect the radiator, should I put some on when I reconnect it?

      There seem to be two types in general, one that you can use for drinking water (non-toxic) and one you can use for non-drinking water (central heating systems?). I used some on water pipes this week for the first time to put some bib taps on. I used ptfe (wound the right way for the thread so it won't unravel when you screw it on), and then the jointing compound. The first try weeped a little so I used more ptfe near the base of the tap thread and the jointing compound, then left it a few hours with the water off, even applying some gentle/ambient heat to help it harden up a little and it was ok in the end on a full pressure cold tap. This is what I used -
