I thought one wasn't supposed to use the same olive again? Will it
seal ok? If so, then I don't need a hose connection.

It will seal absolutely fine, if in doubt - wipe some Plumbers Mait
around the olive.

Good to know. I think I've still got a tin of that stuff somewhere,
but it might have dried out by now. No worries, I'll get a new tin.
