Radiator plug part identification

[laroncete]

Hello everyone, the piece shown below broke when removing it from the T-piece from one of my radiators. The outside screw piece broke in two. It seemed to be closing the steam trap. I need to replace it but don't know what it is called and my local (South London) plumbing supply store didn't have any or knew where I could get them.

Could you please help me identify this and possibly where I could source it?
I tried closing the T-piece with a male end blanking plug but it is leaking.

Thank you very much in advance!

Thanks for your reply. Went on to buy that piece and will try to fit it shortly. I realized that the bottom it fits perfectly into the 15mm pipe but the top bit into the radiator does not fit the piece already inside it. It's a narrower pipe, probably a conversion piece?
Should I remove the old piece inside the towel rad and fit the new one that came with the valve or buy a new straight valve that fits with what's already there?

Thank you

Need to swap the piece into the rad eg the tail

if you don’t want to mess around with the tail just need to swap the valves to this type

Is this a steam system?

I'm not sure the radiator valves Shaun has suggested are steam-rated, though steam is now rather unusual in the UK.

I think it's a regular hot water system with a combi boiler. Unless I'm missing something...

That was made it think it could be steam. What did you mean, out of interest?

I meant the straight valve, sorry. Did not know what it was called, the opposite to the regulating valve...
