Supply pipe help

I am having no luck finding the fitting shown below. It is just a compression fitting with some kind of rubber insert. Used at my house for 3/8" copper supply line to 1/2" sink faucet. This is for the end that goes to the faucet. The end that goes on stop valve has regular nut with ferrule. I know I can get flexible line but was just trying to keep existing copper line.

https://www.supplyhouse.com/Brasscraft-66-6-8X-3-8-OD-Tube-x-1-2-FIP-Brass-Compression-Connector has an NPT thread for the 1/2 inch. That may be ok.

I did not find one with a 1/2 inch female NPS thread in my fairly quick search.

Thanks I can get that to work but I was hoping to find the type with rubber insert like the one I have.

A standard 3/8" riser has a ball end on one side, and takes a 1/2" faucet nut to snug it up. It doesn't need or use a rubber washer.
