Tubing Limitations
• Do not expose Uponor AquaPEX White
tubing to direct sunlight for more
than 30 days; do not expose Uponor
AquaPEX Red or Blue tubing to direct
sunlight for more than 90 days.
• Do not install Uponor AquaPEX
tubing within 6" of any gas appliance
vents, with the exception of double-
wall B-vents or plastic vents (with a
minimum clearance of 1").
• Do not install Uponor AquaPEX tubing
within 12" of non I.C.-rated light
fixtures, unless you have protected the
PEX line with suitable insulation.
Joints and Connections
• Square-cut all tubing ends and ensure
they are free of burrs and debris before
making a connection.
• Ensure fittings and connections comply
with manufacturer recommendations.
• Make transition joints with
manufacturer-approved fittings.
ProPEX Fittings
• Seat the Uponor AquaPEX tubing and
ProPEX Ring fully against the shoulder
of the fitting. The maximum gap
should be no more than the thickness
of a credit card.
• To correct an improper connection, cut
a minimum of 2" from the end of the
tubing and use a new ProPEX Ring.
