Exterior connection water connection

[heavyD]

First, I'm not a plumber so pardon me if I use incorrect terms.

Connected city water (w/ pressure regulator) to flush out pink RV antifreeze and had a blowout under the sink. Connection to passenger side outside shower failed. Connection to driver side exterior shower minor leak but did not detach.

I had to reseat thin metal washer & rubber gasket. Not easy so now looking for another tool to help. You can see I replaced factory clamp (shark bite?) with regular hose clamp. I did that so I could spin the elbow toward me to reseat the washer + gasket.

Attached pic shows white edge flush against black twist on connection now. DS shower connection there is 1/4" - 3/8" space between white edge and black twist on connection. OK for now, but I'm pretty sure will have to fix that one soon too. Not sure if they worked out from travel or just not seated properly from the git go.

Anyone have this happen & replace that elbow connection? Any suggestions to replace? Or stuck with repair?

Thanks in advance for any assistance.

PS
Leaving for 5 days camping this Wednesday, so won't be posting any response after that. Cheers!

Hard to tell because hot water line is blocking, but if you zoom in on the pic, you can see the gap between white edge/lip and the twist on connection
