Going from 10mm JG direct to Radiator TRV?

[Martyn]

So been trying to search this for some time and finding mixed results, I have 10mm JD Speed fit piping coming out the wall and hoping to use it on the original TRVs, things that keep popping up are


these JG stem reducers, but doesn't seem right that the value would go onto the end? wouldn't it cause damage?

or something like this?

Any help be much appreciated

are these the same thing? (nearly half the price) "PEGLER TERRIER CHROME-PLATED BRASS PUSH-FIT REDUCING 90° ELBOW F 10MM X M 15MM (28509)"

sorry I'm unable to post links to Screwfix... as it pops up a message saying that it's most probably spam smh

Yes but them ones the 10mm isn’t removable afterwards so once pushed in you have to cut it
