Troubleshooting ProPEX connections
Trouble-free ProPEX installations begin with a tool that is
maintained in proper working condition. If the tool or segment
fingers are damaged, it is very difficult to make a proper
connection. Refer to the following guidelines to assist with
challenges in the field.
Fittings won’t seal
• Make sure the expander
head is securely tightened
onto the tool.
• Ensure the segment fingers
are not bent. If the head
does not completely close
when the drive unit is fully
retracted or the handles of
the manual tool are open,
replace the head.
• Examine the tool for excess
grease on the segment
fingers. Remove excess
grease prior to making
connections.
• Check the fitting for damage.
Nicks and gouges will cause
the fitting to leak.
• Make sure the internal driver
cone is not damaged or bent.
• Make sure the last expansion
is not held in the expanded
position before the fitting
is inserted. You should feel
some resistance as the fitting
goes into the piping. If you
do not feel any resistance,
the piping may be over
expanded and will require
additional time to shrink
over the fitting.
• Be sure to rotate the tool

turn after each expansion to
avoid deep grooves in the
piping which can result in
potential leak paths.
Expansion is difficult
• Make sure the internal cone
is properly greased.
Expansion head slips out
of piping when making
expansions
• Ensure the piping and
ProPEX ring are dry.
• Make sure that grease is
not getting into the piping.
• Examine the segment
fingers to ensure they
are not damaged or bent.
ProPEX ring slides down
piping during expansion
• Ensure your hands are clean
while handling the piping.
Any sweat or oils on your
hands can act as a lubricant.
Due to the smoothness of
PEX, any form of lubricant
can cause the ProPEX ring
to slide down the piping
during expansion.
