I looked into this and decided to go with thermoplastic tubing. It's nice stuff, much more flexible then Pex.......FYI
Where did you get the thermoplastic tubing?
I think the 200° rating is for when it is under high pressure (85-100psi). On hearth.com forums a user claimed that on an open system (low pressure) it would work at 300+. i have accidentally boiled the water in my outdoor wood boiler lines for several hours and had no problems.
1/2" pex is flexible enough for my needs but i wasnt sure if there was some reaction to wort that i needed to know about (like galvanized).
