I am replacing the shut-off valve under my sink. A compression fitting
connects the valve to the 1/2 inch copper line.

How do I get the old compression ring and old compression nut off the
copper line? Is there a special tool for it? Or, can I just re-use the old
compression ring?

Thanks

Most of the time its ok to reuse. There is a special two part tool to remove
the compression nut/ring - a puller and a corresponding plug that goes into
either 1/2" or 3/4" line.
