Installing bathroom faucet rigid copper riser (water connection line)

Hi-

I purchased some Brasscraft rigid copper water supply lines to connect from the compression valve from the wall to our Kohler faucet.

I understand how to connect the copper riser to the compression valve but there are no directions on the part that connects to the faucet cold and hot itself. It looks like the bullnose piece is perfectly tapered to fit the taper inside the line coming from the faucet but I don't understand how it works.

Is there a nut and some type of washer I need to purchase to hook them together? Sorry for the stupid question. I haven't found a single resource online that explains this and Brasscraft support wasn't helpful.

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.....

When I install a pedestal sink I always install the pedastal last. I always use flex supply lines and leave the tail piece drain nut loose so I can raise the basin a bit. Tighten the tail piece nut after placing the pedastal. It will be harder for you if you use rigid supply lines.

The sink is all done and no leaks! I am going to do the toilet with the oil rubbed bronze hardware but use a braided supply line this time after I paint it. It was a good experience using the copper risers and they look great but its really a pain getting all of the pieces in place for the pedestal sink. Thanks for all the help everyone.
