I just had my plumberadd new water lines. He used Pex for the hot and cold water. How hot can Pex get without bursting?

Thanks

200°F.
For all PEX pipe and tubing, the maximum operating temperature is 200°F. No PEX should be operated at temperatures above 200°F for any length of time. The use of crosslinked polyethylene (PEX) pipe and tubing in high- temperature applications with operating temperatures above 180°F may affect the tubing's design life.
