My guess is it might work up to around 200 PSI.. With water anyways.

Not a bad idea, but the fittings must be brazed.
The little metal ring thingies that are supposed to compress around tubes will not hold refrigerant. If a leak starts, extreme cold suddenly happens, and the tubing will shrink away from the ring thingie and more refrigerant will leak, and more cold, and more leak, etc. I proved it to myself the hard way... It was not one of my better moments.
The re-usable piercing valves from the refrig store (my shop was temporarily out) are almost the same thing, and pretty cheap $5 or so, and have standard 1/4 flare fitting ready to go. They also include adapters to allow good fit on several diameters of tubing.
