INTRODUCTION

The successful use of crosslinked polyethylene (PEX) systems throughout the world in numerous applications, along with the capabilities of PEX pipe and tubing in cold- and hotwater pressure piping environments, have generated significant interest and growth in the usage in these materials across North America.

To answer common questions about PEX materials from installers, designers, builders, engineers and specifiers, as well as the public, this technical note provides an overview of PEX properties and capabilities, the applications and benefits of PEX, and the technical requirements for PEX systems. Several product standards are listed as references.
