Air line disconnects

I’ve just purchased 2 x 10 Gallon air tanks so im looking for a disconnect that can handle 200psi and also seal when nothings inserted

or a way i can simply remove air tanks when not needed

hmmmmm… something like this maybe?

and install some Ball valves that you can close off to keep the pressure in the tank?

Think I’ll squeeze them under the tray bed. Don’t think they really like being used that often. Was more looking for air tool style ones that don’t leak.
