1/2'' MIP to 3/8 compression coupling would do it but I would skip that and replace those valves and install the proper ones. Those are Junk with a capital J. Also never a good idea to reuse supply lines like those vinyl ones.

Something like this might work:
https://www.menards.com/main/plumbi...-valve/2622pcpolfk/p-1444450915084-c-9415.htm
I think there may also be a glue adapter to the valve input as well but cant find a pic of it.

Thanks. What's a good valve? Pipe is cpvc.
Don't see too much CPVC around here but if it were me, I would use the glue valves. I don't like that push connect fittings can spin on the pipe. Just be careful when you cut the pipe as it is known to split/crack.
A cracked pipe would ruin my day for sure and my house is 13 years old now. Should I not use my ratcheting pvc cutter?
Here's what my local home depot has in stock.

This:
Cut all that **** out and glue on at CPVC fitting with MPT (male) or FPT (female) threads. Then thread the appropriate threaded angle stop with 1/4 turn.
There is also a fitting that threads into the angle stop that has an extra outlet to attach your dishwasher line. I does not need its own angle stop. There are also angle stops with two outlets.
Only question I have is what the black lines are...are they the new faucet lines? Why are they facing that direction? Or are you trying to show the ends.
I would have had this done in less time than it is taking to type it except for the run to the hardware/Home Depot/Menards.
Let us know.

Normally the valve would not have a hose attached that you can't remove -- that contraption was done to save the builder a few $$. There is no standard adapter because the old hose is not expected to be reused.
I agree with some above ... with old plumbing often the best thing to do is cut back and attached a threaded fitting. In your case a CPVC female -- that way you can always fix going forward.
For the hot -- they make a "twin" -- the better are two small ball valves that allow you to attach the hot for the dishwasher and the sink. Single for the cold.
It best to have the female CPVC -- a short ****** for each and then the valves.

Except, never screw a metal male fitting into a female plastic one. That's a recipe for it to crack.

This is very good advise. I had a very expensive damage claim with insurance for just such a failure a few years ago. The failure did not appear for several weeks, but the split was evident as soon as the fittings were disassembled.

Concur, concur and yeah, what is that weird end on the black line ?

If you don't go with a mini-ball stop then use the brass craft. When you find they no longer stop when they should or the stem starts leaking you can buy a new one just about anywhere (at least around here), and just replace the stem unit.

That's what Delta uses for 3/8's compression. Ready to use or you can cut them down.

They the cheap Brass Craft stops use a rubber piece for the packing. It takes a "set" after some time and will drip. If you can get the water turned off AND drained out, remove the rubber piece and install it backwards. nor more leak !
If I EVER replace a stop valve again, the pipe end will be threaded or compression (now that I know you CAN remove the ferrule), 1/4 turn ball valve and 3/8 compression on the outlet.
