Peter that is my option if I can’t find one but i would prefer to get a proper one if possible.

I found it strange that the female nuts are UNF thread and BSF spanner size and the male.fittings are UNF thread and AF spanner size.

Despite hours of searchihg with no luck i have made one out of a King Dick heavy duty ring spanner this has a thicker wall than a normal spanner..

Try a 8mm flare  (in theory only 2 thou. slacker)     modern tube nuts will use 8mm stock.

5/16 BSF spanner is 13.34mm  surely?

5/16" AF would be 7.9375mm but that isn't the spanner Richard requires.

8mm  tube nut would have a tiny pipe running through it!

I am almost certain I use a 8mm flare when changing thermocouple on boiler gas valve.

It was 5/16” Whitworth i needed which is 15.25mm i tried a 15mm spanner but that was too small.
