Introduction

The successful use of crosslinked polyethylene (PEX) systems throughout the world, along with the capabilities of PEX piping in cold- and hot-water 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 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.
