Get a yorkshire 22 x 3/4 slip or some 3/4 olives to use with compression fittings.

Why do you think you have ¾"? It's outside diameter is 21.5mm whereas that of 22mm is, er, 22mm. So you'd have a job telling.... Imperial sized tube hasn't been used since about 1973? I think.

22mm olives feel very loose on ¾" tube, and there's still quite a lot of the old stuff around here.
