You need faucet supply nuts they should have came on the new faucet or packed separately in the box.
You can use braided flex supplies instead. The are available in different finishes.
Whichever way you go, be sure to have a backup wrench on the faucet line so you dont twist the soft tubing

Ok, I purchased some 1/2" faucet coupling nuts. So I just slide it up the metal riser like in my pic and thread it to the hot or cold copper line coming from the faucet correct? Is the idea that the copper from both lines is a bit soft and when I use the coupler nuts it squishes them a bit to make a water type seal?



thx!

That's correct. Be sure they mate as square as possible. Again, use a back up wrench.
I understand this is a ped lav? You will be very tight on space. I'll suggest you consider braided flex connectors. They'll save you some grief.....
