I have to fit a 22mm compression fitting valve into a copper pipe which may
be either 22mm or 3/4 inch. Is a 22mm compression fitting compatible with a
3/4 inch pipe should this prove to be the case. I'd rather not cut the pipe
and try to see if it fits because if it doesn't that would be most
Thanks for all helpful replies.
Remember that 22mm is the o/d of modern stuff and 3/4" is the i/d of the
old stuff, older pipes were also a heavier gauge so the difference is
less than you think but just enough that a special olive is required. As
already mentioned posted, plumbers' merchants are well used to this
