See how the engineer has hacksawed the first few mil off the inner
thread,
to try and get it to fit

Yup, this seems to be the key to the puzzle.

It wasn't one of those "could have happened to anyone" moments, he
deliberately took a hacksaw to it.


Why cut a few millimetres off the thread? Why not pack it with fibre or
neoprene washers to make it tight? Seems really silly, to me anyway, not to
try and place a couple of washers in the fitting, or even sealant solution
around it, then tighten it back into place. Weird engineers now'a'days.
