ttings
Uponor ProPEX
®
ttings are available in both EP and LF brass and are tested and listed to:
• ASTM F1960 Standard Specication for Cold Expansion Fittings with PEX Reinforcing Rings for Use With Cross-linked
Polyethylene (PEX) Piping
• CAN/CSA B137.5 Crosslinked Polyethylene (PEX) Piping Systems for Pressure Applications
Uponor ProPEX EP ttings
Accessibility
Based on Uponor’s review
of the International Plumbing
Code (IPC), National Plumbing
Code of Canada (NPCC)
and Uniform Plumbing
Code (UPC), there are no
requirements for direct access
to Uponor ProPEX ttings (i.e.,
ASTM F1960 and CAN/CSA
B137.5). Thus, ProPEX ttings
(which includes Uponor's
mulitport tees) may be placed
behind drywall or other
coverings without the need for
openings or similar means of
direct access to the ttings.
However, codes require that
an operating valve must be
accessible. Thus, a valve or
similar operable component
that incorporates Uponor
ProPEX connections must be
accessible.
Performance
EP is a high-performance
thermoplastic material that has
superior mechanical, chemical
and thermal properties which
provide dimensional stability
in demanding applications,
including areas of high stress,
heat and moisture.
Uponor EP ttings comply with
NSF/ANSI 61 health effects
requirements when tested
at temperatures up to and
including 180ºF/82.2ºC
(i.e., commercial hot water).
Durable
Resistant to corrosion, pitting
and scaling, Uponor EP
products are designed for any
plumbing — and even heating
— application, whether
residential or commercial.
Note: Do not expose EP
ttings to direct sunlight for
more than 30 days.
Lead free
EP ttings are the ideal
solution to lead-free
requirements and are even
approved for direct burial
in soil, making installation
options endless.
Cost effective
Uponor EP is a more cost-
effective option because it
offers a stable material cost
and is not subject to the wide
price uctuations of metal.
