Is it ok to use a 22mm compression fitting on (20mm)/(3/4'') pipe to connect to modern everyday 22mm copper? It's holding this far, took a bit of torquing!

Its holding so far?
Stupid question....
If using a smaller olive in a 22mm compression fitting, do I just need to apply extra turns?
Thanks
I have just renewed some black pipe marked 3/4inch and a 3/4olive wouldnt go on it. I bought a 3/4inch to 20mm connector followed by a 20mm to 1/2inch stopcock.

Got to speak as I find. I will always use a 3/4 olive, or solder an adapter, but a 22mm olive will seal quite often. That's from experience as I did it myself in a miss spent youth. Rebel.
But if it blows, you'll only have yourself to blame. I would never, ever do it now. Genuinely.
Same here. I have had times where put 22 brass olive on 22 pipe tightened up and pipe slides out!:blush2::blush2:. Not had my spinach!always have imperial to metric fittings in tha van along with imerial olives

9mm I guess ! LolNext bit of 3/4 pipe I find I'm double checking.....could be in for a long wait. I did find a pipe size that I've never ever come across before. Found it about a month back. Leaking joint on a 10mm compression. Took it out, and went to replace it. (long story short, the pipe wasn't 10mm or 8, or 12) but some random size in between 10 and 8mm.
So I just had to remake the joint that was there with a new olive, and ptfe on the olive. (This was ten at night).
