Alvin, it seems to have done exactly what you describe, but I don't know what causes that action. I tried to fit a compression sleeve but there was not enough room. So I pushed the copper tubing through, pushed it to the bottom and tightened the nut tube and miraculously - no leaks!
By the way Tim, I can see the link now - that looks exactly like what I have.
