Unsure on how to fit the TRV to 15mm copper pipes

[Smartwater]

Hi,

I need some advice. I am trying to replace the manual radiator valves on a towelrail with a TRV:

I ordered a Myson 2TRV15SN, and the tail seems to be identical with the current setup, however I am not sure who to attach the copper pipe at the bottom. This doesn't seem like a standard compression fitting.

How do I fit this?

Thanks

You would have to remove the old nut and olive and install the new ones

The bottom piece is what is confusing me, that is obviously not a fitting for a nut and olive. Would I need some 1/2"-15mm coupler, something like this one?

AS Shaun has said, you need to pull the old olive off the pipe, remove the old nut, fit the new chrome nut and new olive.
No additional fittings required

Yes it is a fitting for a nut and olive just reversed eg threads on the nut

oh right, that's simple, the nut is already there!

Thanks!

Is there a term for fitting nut and olive that way round?

I only managed to get hold of one Myson 2TRV15SN, but I need two more. I find it very difficult to locate such TRVs without heads online. Can someone recommend an alternative TRV?

Thank you
