In a recent thread, the consensus seemed to be that liquid PTFE was superior
to tape for sealing (for example) the threads on radiator tails. It is also
quite a lot more expensive!
Can I ask those who use the liquid where you normally get it, and in what
How much do I need for 10 radiators (20 tails)?
I see that Screwfix sell 50 ml for about a tenner (a bit cheaper at
Toolstation) or you can get 250 ml from Plumb Center for about £19 + VAT.
What is its shelf life, once opened?
[Also, can anyone tell me where I can get a 1/2"BSP tap (as in tap and die!)
to clean up the threads in my rads prior to fitting new valves?]
