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 think they are just standard pre-made copper line sets (copper tubing,
flared ends with flared nuts and overall insulation) that happen to be
sold by a company named "pexsupply"




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