Al, Maybe I don't understand you, or maybe I don't understand Shark bite or pex.
If you have Copper line, and you are installing a valve, or replacing an existing valve, you need a shark bite valve. If you have pex, or are running new lines, then you can use either a shark bite, or pex valve on a pex line. I believe that there are specific valves for pex, but I am pretty sure that shark bite valves will work on either Copper or pex. Hope I haven't confused things. -- Blue skies.
