Installation Guide

PEX Tubing
PEX tubing is cross-linked, high-density polyethylene. It’s available in white, red, or blue colors for easy
identication of hot and cold water lines.
Apollo PEX tubing is type PEX-B (PE-Xb, PEXb). The silane method, also called the “moisture cure” method, results
in PEX-B. In this method, cross-linking is performed in a secondary post-extrusion process, producing cross-links
between a cross-linking agent. The process is accelerated with heat and moisture. The cross-linked bonds are
formed through silanol condensation between two grafted vinyltrimethoxysilane (VTMS) units, connecting the
polyethylene chains with C-C-Si-O-Si-C-C bridges.

PEX tubing is for use in hot and cold potable water distribution systems as well as hydronic radiant heating
systems. PEX tubing can also be used in “continuously recirculating” plumbing systems up to 140°F while
maintaining chlorine resistance.

Installation:
To cut PEX tubing, use a PEX tubing cutter and cut at a 90° angle. Clear the cut end of any burrs or debris. PEX tubing can be run through holes drilled into the center of
studs or by using straps and hangers. Bend supports can be used to make bends and angles instead of having to cut the tubing and use fittings. A variety of barb fittings
or push type fittings can be used with PEX tubing. Do not expose PEX tubing to direct sunlight.
It is recommended to insulate hot water lines with standard foam polyethylene pipe insulation to prevent heat loss.
If installing in an area that experiences harsh winters, it’s recommended to insulate both hot and cold water lines to
prevent freezing.
