@The Real Pin 5 Dan I worked on a system once and the Gas supply was 54mm in what looked like Aluminium or stainless and was pressfit, you could rotate the fittings when pressed and wouldn't leak, any Idea what that system is called ?
Guess you saw my post before I realised it was the open forum. .
Normal press can move quite a bit. Especially at that size. It's not supposed to though. I was bloody grateful that lot didn't leak because getting the press gun up there and on the fittings with the 42mm and 54mm slings was bloody painful and awkward
