Hello,

What size spanners do you need for 22mm straight compression fittings?
The nuts are 32mm but what about the flange on the middle of the body?
I measured it with a vernier calliper and I think it was 28.5mm, which
seems an awkward size. Rounding that up to 29mm, I could not find any
29mm spanners anywhere. Would a 30mm spanner be too big or do you
"cheat" and use adjustable ones?

Thanks,
Stephen

Thats 1 & 1/8th inch, and ISTR thats a whitworth size.

1 & 1/8th works out to 28.6 mm, which looks about right for the OP.
About 20 years ago I bought some spanners with obscure sizes and only
now am I understanding why they were made. One of them was 29 mm, but I
can't remember the others and it is dark and cold where they are stored :-)
