Anyway, this leads me to my question. Does it matter if the new nut (3/16 M10 x 1mm short male) is threaded all the way down and the old one isn't? I have tried the new nut in both the connection to the flexi-hose and to the new cylinder and it seams to fit in both fine, but this is without the single bubble flare on the end.
See below the new nut and the old corroded one. Cheers, Barry.
