Making ProPEX Connections
Tools Needed
•
ProPEX Air Expander Tool
•
Properly sized expander head, hand-tightened on the tool
•
Tubing cutter designed for plastic tubing
max
¹⁄₁₆
"
1. Square cut the PEX tubing perpendicu-
lar to the length of the tubing. Remove
all excess material or burrs that might
affect the fitting connection.
2. Slide the PEX ring over the end of the
tubing. Extend the end of the ring
over the end of the tubing no more
than
¹⁄₁₆
of an inch (1mm).
Expanding the PEX Ring
3. Slide the expander head into the tub-
ing until it stops. Full expansions are
necessary to make a proper connec-
tion. Press the trigger to expand.
Release the trigger, remove the head
from the tubing and rotate it
¹⁄₈
turn.
Slide the tool head into the tubing in
the newly rotated position and
expand again.
Important:
Rotate the tool
¹⁄₈
turn after
each expansion to provide smooth and
even expansion of the tubing. If the
head is not repositioned after each
expansion, the segments on the tool
head may cause deep grooves in the
tubing. These grooves can result in
potential leak paths.
