...do the AF nut sizes on 15mm compression fittings vary by so much? About
1.5mm between the smallest and largest here. All new. The threads seem the

If space is tight, you need a good spanner fit. And I hate adjustables.

The big forged "wrap around" compression spanners seem to work on all
the variations, but yup there is a fair amount of variation for a a
