Undoing Doubles

[Compressor]

Hi:

I have disassembled my double 80s to singles.
I have a left and right handed thermo DIN valves without the center manifold or connecting part. I need to find the plug that goes into the valve side so that the tanks can be filled. I would appreciate any input on where I can buy these.

Appreciate that very much. Not sure why I did not think of them myself in the first place.
