Hi,

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

Thanks!

Sam

I don't know about PEX, but some plastics will let gas pass through it. *The
2 liter and like Coke bottles will let the co2 out. *If you look at a bunch
of them in a store, some will seem to have more it them than others. *The
ones that look fuller are the old ones.

That's a joke I hope. *Or do you really think water is a compressible
liquid....

Do you really think that the flexible plastic
container that soda is typically dispensed
in might play a role in such observations
when the pressure inside decreases...
