Don't forget that compression fittings are BSP sized, therefore the

I did wonder that when I measured 28.5mm but then I thought if the
pipe is metric, surely the fittings will be too; I was forgetting that
15 and 22 mm pipe are essentially 1/2 and 3/4 inch pipe.

15mm and 1/2" are quite close: 22mm and 3/4" ain't. But it's the threads
on compression fittings which are BSP - only the bore and olive sizes were
altered for metric tube.
