Well, I've never had a compression joint leak and those I've taken

isn't deformed I don't know what is.
I'm using "deformed" in the sense of "taken beyond its elastic limit".
You may be using some other meaning.


perhaps deformed was too strong a term for /compressed/ ?


No, compressed is something different. To my mind it implies the ability
to spring back, which pipe won't do after an olive has been squashed on
to it.

Compressed is just the opposite of tensed...

c.f. compressive load and tensile load
