Introduction
This handbook is intended to train and educate the professional contractor on the recommended techniques of installing NIBCO piping
systems. To insure that your installation is successful, please read this manual completely. If you are unsure about any of the instruc-
tions in this manual, please contact NIBCO at 888.446.4226. NIBCO is not responsible for any misinterpretations or deviations from this
manual. We recommend that you also contact your local plumbing officials to determine code acceptance of PEX systems in your area.
The NIBCO
®
PEX Manufacturing Process
Cross-linking is the process that gives NIBCO
®
PEX tubing its superior characteristics. The long, simple chains in a polyethylene mol-
ecule are altered to form a more stable, three-dimensional network. This process changes the material from a thermoplastic into a ther-
moset. A thermoset differs from a thermoplastic because a thermoset cannot be melted and then reformed. This change in molecular
structure creates a polyethylene product with enhanced mechanical properties. Many manufacturers use a chemical additive to activate
the cross-linking process, but NIBCO employs a sterile, electron beam process that provides superior properties. This process, which is
called PEX-c, delivers the highest quality PEX tubing available today, while reducing the use of chemicals.
NIBCO
®
PEX is a Complete System
NIBCO
®
PEX tubing, fittings, valves, and manifolds are designed to be used as a complete system. Therefore, NIBCO cannot guarantee
that tubing and/or components from other systems are compatible for use with the NIBCO
®
PEX system. NIBCO offers more versatility
with the choice of three different connections - copper crimp ring, copper crimp sleeve, or stainless steel sleeve.
Standards and Approvals
NIBCO
®
PEX is an outside diameter controlled tubing of one standard dimension ratio (SDR 9) that is manufactured to comply with the
requirements of CSA B137.5, and ASTM F876. NIBCO
®
PEX insert fittings and copper crimp rings are manufactured to comply with
CSA B137.5 and ASTM F1807. NIBCO
®
PEX tubing, fittings, and crimp rings are tested as a system to the requirements of ASTM F877.
NIBCO
®
PEX tubing and components have been tested and listed in the Uniform Plumbing Code (UPC) by the International Association
of Plumbing and Mechanical Officials (IAPMO) for compliance to NSF/ANSI 14 and NSF/ANSI 61.
Lead-Free*
By using NIBCO PEX and NIBCO poly or lead free bronze fittings, a lead-free plumbing system is achieved.*
*Lead Free refers to the wetted surface of pipe, fittings and fixtures in potable water systems that have a weighted average lead content
≤
0.25% per the Safe Drinking Water Act (Sec.
1417) amended 1-4-2011 and other equivalent state regulations.
