I need to replace a failed TRV on a radiator that has 8mm microbore copper piping. The radiator/TRV/piping are all original and have been in place for approx 30 years.
I know that I’ll need a 15mm-8mm reducer as all modern TRV’s have 15mm connectors (is that right?).
However I’m unsure what type of 15mm-8mm reducer to use in conjunction with the new TRV; there seems to be 2 types.......

Which one will I need???
I’ve changed one of these TRVs about 10 years ago but that was in conjunction with moving the radiator to another wall and adding new pipework, which was increased to 10mm.
I also recall having to remove/replace the internal connection from the radiator itself so that it would accommodate the new TRV fitting/size etc.
It’s so long ago I’m a little uncertain of what details the job entails. Anyone care to enlighten me please.
Also, are these TRVs any good;
