PEX pipe in a basement. Note the bend: PEX is more flexible than copper.

Cross-linked polyethylene, commonly abbreviated PEX, XPE, or XLPE, is a form of polyethylene with cross-links.

It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, and insulation for high tension (high voltage) electrical cables.

It is also used for natural gas and offshore oil applications, chemical transportation, and transportation of sewage and slurries.

PEX is an alternative to polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), or copper tubing for use as residential water pipes.
