Fire-resistant Standards
For a complete list of the fire-resistant
standards, codes and listings, refer to
the Uponor Plumbing Design Assistance
Manual (PDAM).
Firestop Listings
Numerous firestop manufacturers have
tested their products with PEX tubing.
These tests establish the installation
procedures for installing the firestop
around PEX tubing at the penetration.
The type of penetration (e.g., wall, floor
or ceiling) determines how these test
assembly sections are divided.
Not all caulks are approved for all
penetrations. Be sure to seal the
penetration in accordance with the
appropriate test assembly, using the
type of firestop material recommended
by the firestop manufacturer. Larger
penetrations may not allow the use of
some caulk-type of firestops — a wrap
or collar assembly may be required. Refer
to the respective firestop manufacturer
for more information on appropriate
applications of their products.
Typical firestop manufacturers include:
• 3M™
• Hilti®
• HOLDRITE HydroFlame™
• Passive Fire Protection Partners
• ProSet Systems
• Tremco®
Applications
Recirculation Systems
Based on our extensive history of use and
testing, Uponor provides the following
guidelines for using Uponor PEX tubing
and corresponding fitting systems in
recirculating systems.
• Uponor AquaPEX is suitable for use in:
o Recirculation systems operating up
to 140ºF (60ºC)
o Timed, sensor-activated or self-
activated recirculation systems
operating at temperatures not
exceeding 140ºF (60ºC)
o Continuous recirculation systems
operating at temperatures not
exceeding 140ºF (60ºC)
Note: Uponor does not promote the
use of continuous recirculation due to
excessive energy waste.
• Uponor AquaPEX White tubing is
marked with the following designation
as required by the most recent edition
of ASTM F876: PEX 5106. The first
digit indicates chlorine-resistance
testing (“5” means compliance with
ASTM F876, Chlorine-resistance
Testing for Continuous Recirculating
Systems).
• Do not exceed the published
temperature and pressure ratings of
the tubing.
• Using recirculation systems may
increase the risk of scalding. Therefore,
Uponor recommends limiting the
delivered water temperature to 120ºF
(49ºC) in all cases.
