While radiator removed for decorating, valve started dribbling from its opening (no reason, as had been OK for days).
I went to B&Q to get a suitable brass blanking cap and screwed this in place with 4-5 turns PFTE tape (correct direction on male thread), but it's still dribbling, especially when I repressurise hot water system (which I obviously need).
Do I need to repeat with MORE turns of PFTE tape or try something else? (I know I will have to strip off this PFTE tape when i unscrew the cap)

The connection you are talking of here is the female part of a cone joint (the male is on the radiator) The joint normally seals on the tapered faces of the cone, not on the flat end as you are 'asking' it to do now. Go to a 'proper plumbers merchant' ask them for a rubber disc insert for the blanking cap and use that. When you re-connect the rad, ensure that the faces of the tapers are super clean, check the joint as it heats up.

If solutions a million or 2 do no longer remedy your undertaking try this. on the backside of each end of the radiator the place the pipe joins the you may desire to have a valve. turn them the two off, for one in all them you are able to wish a pair of pliers because it somewhat is not any longer often adjusted. this could seal this radiator from something of the equipment then unscrew the full valve (no longer basically the bleed screw) and take it to a B& Q, Wicks or a plumbers provider provider (they are going to be plenty greater fee-effective) and get a replace. greater modern form have rubber washers so the do no longer want any PTFE tape on the thread. do no longer overlook to coach on the two valves after installation new piece.

Be certain that the valve is leaking from the opening, it may be leaking from around the base of the spindle on top of the valve and running down, there is a nut at the base of the spindle, if it won't tighten, take it off and put ptfe in the space underneath, tighten the nut back on, not too tight or you will not be able to turn the valve spindle.

If it's an old type of thermostatic valve it may not have a positive shut-off and may be opening at low room temperature, since the room is now unheated. However the cap and thread tape should have sealed it!

If you're sure it is coming out of the opening then more PTFE should seal it - make sure you have not cross threaded it. Maybe somone before you has crossthreaded it; in which case it will have to be replaced.

pop a tap washer inside the end cap you have fitted and tighten as usual
