There are plastic and brass rings to go on the tubing. I am guessing the
brass are for copper, and the plastic are for plastic. Is that correct?
There also little lipped brass tubes; they go in plastic tubing? Can I
use these with PEX?


The ones I bought are a gray plastic and specifically say they can be used
with pex or copper or cpvc. I don' tknow about the others, but if the od of
the tubing is the right size, I suspect they would work but can't say for
certain.
