Hi
I bought one of these (right-angled version) and noticed that the original nuts on the 22mm pipework didn't fit. Then I saw on the body of the unit "3/4". Testing it I put some new 22mm pipe in and tightened up the nut but it seemed I needed to tighten really tight in order for the olive to grip the pipe and stop it rotating/moving. Obviously 3/4 of an inch is quite a bit smaller than 22mm but I'm guessing maybe there is some subtly about internal/external diamter and in fact these fittings are compatible?
So the question is, is this thing ok to fit to 22mm (just tighten up more than usual?)
