Hi,

I just had an outdoor faucet fail due to a cracked compression nut.
The nut and valve have been removed and in looking at the remaining
pipe I see the olive is secured to the pipe. The olive itself spins
in place but cannot be slid off of the pipe itself. My guess is that
some fitting with a larger end designed to hold the olive in place was
welded to the main assembly.

I'm curious first off if anyone knows what this type of compression
arrangement is officially called so I can start making some better
searches about it?

Secondly I wonder if anyone knows enough about these type of
connections to point me in a direction as to how to go about fixing
one?

Thanks

Scott
