Will double check the rad - I'm the king of cheap internet crap!
Thanks for the sealant tip, worth a try. Roughened thread? is that with a wire brush?
really appreciate the advice.
I have a new towel rail radiator but keep getting leaks when I install it. It comes with a threaded tail. I wrapped the tail in plenty of PTFE but have found I can't tighten it just keeps going up into the radiator. needless to say this leaks.
I then bought this tail...
