Why not simply screwing the hex plug in your DIN valve, so that a standard yoke hose can be used for filling?
This is what I do on my 15 liters Faber steel tank...
As my valve is double post, I usually leave the hex insert permanently screwed in one of the two.
So when they fill the tank they simply use the valve which fits their comprosser, without any adaptor.
However, if you have just one post, screwing in the hex insert takes less than one minute.

I don't believe this will work for my tanks (admittedly I haven't tried it though).
 
I’m sure your guy is using something like these

they work fine if the prints are good and they are tight.

It works if your DIN valve is the 200-232 bar version (the only I have ever seen). It does not work if your DIN valve is the 300 bar version (longer screw).
 
I have frequently had yoke fills to 3300 psi which cool to 3000 psi. I would say that if you are getting free 3000 fills into your doubles that are 3500 I would be happy.

I'm not near my tanks, but here's a picture. I'm not sure what valves these are? They have the little dimple in the back for what looks like a yoke valve to go, but they are 3500 psi tanks...I've never noticed other valves.

Some valves have the dimple even though they are 300 bar. The valves look like those made by OMS. I know they made face sealing cross over isolators. Perhaps other mfg.
