I'm at the hardware store right now and was wondering which tubing I should get. The clear vinyl one says it handles chemicals, gases, and liquids; but do not use with ice makers
The other is polyethylene tubing that says resistant to most acids and akalis; good for ice makers or water lines.
If it is for hot make sure it is reinforced else the tube get soft when it heats up and can kink really easily. I just replaced a bunch of cheap clear hose with reinforced vinyl on the chilling side and silicone on the wort side.
