Yeah I do need a coupling but for it. Anyone know where to look? Googling valve connectors brings up mainly plumbing results and the ord air one I’ve not a clue with the size!
I got an brass air line extention coupling that is no more than what you would see on twinned up wheels on a drive or trailer axle, same fit as a tyre valve. mine obtained from M1 J13 Cawley Crossing truckstop.
