Its a quick disconnect for the standard tire air valve, the problem is it doesn't fit wheels where the valve is close to a spoke because its so bulky. I got it for $40 so i thought throwing a different chuck wouldnt be a bad deal. https://www.amazon.com/dp/B075RQHLKZ?tag=atomicindus08-20I think you on the right track. There is probably some sort of pipe dope or other sealant which has hardened with the passage of time. I would apply a propane torch to the silver hex. Obviously try not to burn up the rubber hose.
But, isn't that a quick disconnect coupler in your picture? The chuck is the piece that you push onto a tire valve stem. Are you trying to change from the silver Milton coupler to something like a Prevost ?

Would a box end fit over the quick connector? Doubt it.It’s in the background
Two wrenches.
I agree, a box end would not fit and i doubt you could get a flare wrench on the brass hex either because of the ferrule on the hose.Would a box end fit over the quick connector? Doubt it.
A knipex plier wrench would work better on the brass and not mar things like other pliers or pipe wrenches He appears to be using raised panel craftsman, so a better fitting wrench would also be better.Does anybody suggest any other tool?
I by chance someone did use loctite or similar, they will all let go if heated to 400 deg F so a heat gun or small butane torch will easily do it.I am trying to put a euro style air chuck on my Milton inflator. The chuck that is on there now has some sort of sealant on it. Does this need to be heated to release? The brass corners started to round off when I tried to remove it.
+1!Would a box end fit over the quick connector? Doubt it.

Go wild and use a small pipe wrench?


This. One on the fitting on the hose, the other on the chuck.Two wrenches.
Otherwise put the brass end in a vise and wrench off the fitting. BTDT.
And stop Euronating on everything, Calvin.
