Tap tails, connection advice please.

slowly getting dizzy from going round the bend... Seem to have an array of fittings except the one i need grrr!  What do i need to attach to a copper pipe to allow this to connect please?  I can solder, but compression, or push would do me equally as well.  Got some lovely Hep20 tails, but the connector doesn’t fit my bath mixer controller.  Thin hep is 10mm and the mixer is 8mm.  Ta.

One of these fits, would that be the right type of fitting to use?

Looks like it, should be parallel thread with flat end to seat on a rubber washer in the hose coupling
