No. PEX cannot handle boiling water for sustained periods. It will expand, kink, and potentially burst.
The number one risk of sending systems is a phenomenon called thermal shock .
The answer is more nuanced than a simple yes or no. While boiling water is not universally "bad," it can cause serious—and expensive—damage to certain types of plumbing systems.

It seems logical—high heat dissolves grease, right? But is a classic DIY move that is as often problematic as it is useful. While it can be a fantastic, natural solution for certain issues, it can cause catastrophic damage in other scenarios.
