Correct will not lock over the flange, have cleaned the valve also. it is a plastic coupler on a can of leak detector. I have looked at the brass ones an they seem bigger. Will get one next time I am in town.
Thanks
Hay Caddy OLtimer, I bought a new small can recharge hose also an it does not fit either, Any Ideas as to why? An can I find a new one to fit?
Thanks, Be Safe
