The strength of Uponor EP
Uponor EP is made from UDEL
®
polysulfone, Radel R
®
polyphenylsulfone or Acudel
®
modied polyphenylsulfone. These materials
are part of a family of polymers that have been used successfully in the demanding environments of medical appliance, aerospace
and plumbing for many years. In fact, lab tests prove the Uponor 2" ProPEX EP Tee and ProPEX connection are able to withstand
up to 2,900 lbs. of pull force without failure.
Uponor ProPEX LF
brass ttings
Uponor offers a complete line
of LF brass transition ttings,
valves, stub-outs, water-heater
connectors and wall boxes.
• All Uponor LF brass products
comply with NSF/ANSI 61
Annex G, NSF/ANSI 372 and
conform to the lead-content
requirements for “lead-
free” plumbing as dened
by California, Vermont,
Maryland and Louisiana
state laws as well as the U.S.
Safe Drinking Water Act,
effective January 2014.
• All Uponor LF brass
ttings marked as NSFus-
pw-G comply with the
dezincication resistance
(DZR) and stress-corrosion
cracking (SCC) requirements
of Sections 5.8.1 and 5.8.2
per the current NSF 14
Standard.
• Uponor’s LF brass is
approved for direct burial in
soil per NSF/ANSI Standard
14 testing which established
minimum performance
criteria for DZR/SCC
resistance for PEX ttings
intended for potable water.
Soldering
• When soldering LF brass
ttings, Uponor recommends
using a lead-free ux and
solder which meet the
requirements of NSF/ANSI
372 or NSF/ANSI 61 Annex
G. Please refer to the solder
and ux manufacturer for
details on properly soldering
lead-free brass materials.
Fittings by others
Uponor PEX piping can
be used with any type of
SDR9 PEX tting, including
compression ttings.
Compression ttings must be
installed with an insert stiffener
to ensure the pipe wall doesn’t
collapse under compression,
compromising the connection.
Note that Uponor cautions the
use of other manufacturer’s
PEX pipe with Uponor ProPEX
rings as well as using other’s
expansion rings with Uponor
PEX pipe. Because of the
lower degree and uniformity
of crosslinking in PEX-b and
PEX-c pipe, stress cracking
of the PEX-b and PEX-c
pipe wall can occur during
expansion, compromising
the strength of the tting
connection. Additionally, the
25-year limited warranty
for Uponor PEX systems is
only valid when using both
Uponor PEX pipe and Uponor
ProPEX ttings. Mixing
Uponor ProPEX rings with
other manufacturers’ PEX
pipe or other manufacturers’
expansion rings with
Uponor PEX pipe will limit
the warranty. For complete
warranty details, refer to
uponorpro.com/warranties.
Note: When transitioning
from copper to PEX, Uponor
recommends the use of
ProPEX LF brass copper
press adapters. Standard
Uponor LF brass sweat
adapters cannot be pressed
as they are a different material.
