Hi Neal,

Quest is the brand name, and it is in the same spot as the copper tubeing in our home depot, it uses compression type fittings to attach to the copper, I have used it extensivly when I was in the RV business and have replace a lot of the piping in our Mobil home with it and it is good stuff, just cut your copper line, slip on the nut, then the cone and the ring and tighten with a cresent wrench, I have never had a leak from it, and like I said, I have used it extensivly. Forgot to mention, it is semi flexible and pretty easy to work with, you can cut it with a pocket knife.

Let me know if I can help more.
