Replacing radiator nut

[SubtleD]

Hi all,

I removed a radiator for decorating and when coming to re-fit it seems as though the nut has become cross-threaded and won't go back on properly (I can screw a spare nut onto the TRV end with no problems so I'm pretty sure it's the radiator that's the problem).

Does anyone have any ideas as to the best way to resolve this? Can I use an olive puller on the radiator to get the old olive and nut off and then replace with new, or is that likely to cause more damage? I've attached a picture to show the bit I'm talking about.

Cheers!

After doing a bit more digging I think I actually want to remove and replace the whole tail with e.g. https://www.ebay.co.uk/itm/PAIR-of-Radiator-Lockshield-Valve-Tails-ONLY-1-2-x-3-4-/264163363998

Is that right?
