22mm into 3/4"

[Jeremy Goff]

Will 22mm pipe with olive fit into a 3/4" compression fitting?

TIA Jerry

I used a 22mm yorkshire fitting on some 3/4" copper pipe the other day - If that helps!

I want to go the other way: 22mm pipe into 3/4" fitting

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Jeremy Goff" saying something like:

You'll need to replace the fitting with a 22mm one. What is the fitting, T, Elbow, what?

To avoid too much faffing around, if the existing fitting is awkward, you could terminate the new 3/4" pipe short and use a straight 22mm connector - one end to the 22mm existing fitting and the 3/4" pipe into the the other side with a 3/4" nut and olive.

[Roger Mills]

It *might* - but it will be tight, and you'll need a 22mm olive anyway.

A 22mm pipe is slightly (but not much) bigger than a 3/4" pipe. Going the other way is easy - you can fit a 3/4" pipe into a 22mm fitting as long as you use a special olive.

[John Rumm]

No, the 22mm is slightly larger...

(the other way round will work - h you ought to use a thicker olive in that case, but you can often get away with the standard 22mm one)
