Hi,

Is there such thing as PEX that you can use instead of copper for HVAC
refrigerant?

Thanks!

Don't know personally but googled it up and got hits:

http://www.pexsupply.com/Refrigerant...r-HVAC-1690000

I would have worried about embrittlement at low temperatures and higher
pressures but guess it can be handled.

If you look at the picture, the pipes may be made by PEX but I can see a
copper liner exposed at the ends of the piping.
