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

I have a massive jumbo adjustable spanner I picked up years ago. Have
also been known to use a mole wrench, adjustable pliers etc.
