Zurn PEX CR Fitting System
Zurn PEX CR fittings are molded from a blend of highly engineered
polymers. The inherent qualities of the polymers make fittings highly
resistant to chlorine and other chemicals present in potable water.
Zurn PEX CR fittings are a superior alternative to metallic fittings in
areas with localized aggressive water chemistries.

Zurn PEX CR Installation Precautions
When working with Zurn PEX CR fittings, we recommend following the
practices listed below to maximize the life of the system.
Note:
The Zurn
PEX recommendation is intended to provide customers with knowledge
for the safe handling, storage, and installation of the Zurn PEX CR
fittings. While this list is not compre hensive, an under standing of the
strengths and limitations of the Zurn PEX CR fittings will help to ensure
that they maintain optimum performance characteristics throughout
the life of the system.
• Zurn PEX CR fittings should only be used in operating conditions that
are consistent with temperature and pressure ratings of the tube as
well as applicable standards.
• Zurn PEX CR fittings should not be painted.
• Zurn PEX CR fittings should not be exposed to direct ultraviolet light.
When possible, protect fittings with an opaque covering.
• Zurn PEX CR male pipe threads must only use PTFE tape as a
thread sealant.
• Zurn PEX CR fittings should not be exposed to cleaners, chemicals,
solvents, sealants, or glues as they could be damaged from contact.
• Zurn PEX CR fittings should always be stored in clean, preferably
lined, bins or containers.
• Zurn PEX CR Fittings must be protected from contact with spray foam
insulation or sealants.

not comprehensive, an under standing of the strengths and limitations
of the Zurn PEX XL
fittings will help to ensure that they maintain
optimum performance characteristics throughout the life of the system.
• Zurn PEX XL fittings should only be used in operating conditions
that are consistent with temperature and pressure ratings as well
as applicable standards.
• Zurn PEX XL fittings should not be used in reverse osmosis
systems.
• Zurn PEX XL fittings should not be used in areas with known
localized aggressive water chemistries.
Fitting Systems
Zurn PEX is a relatively inert material and is therefore joined by mechanical connections. Zurn’s mechanical connections consist
of an insert fitting and a clamp system to make the connection between the tubing and the fitting. To suit your installation needs
Zurn offers two choices for insert fittings – Zurn PEX CR and Zurn PEX XL.
