• If you anticipate the ProPEX
ring may possibly slide down,
position the ring slightly
farther over the end of the
piping and make the first
couple of expansions slowly.
Once the ring and the piping
begin to expand together,
continue with the normal
number and type
of expansions.
• Place your thumb against the
ProPEX ring to help support it
and feel for any movement.
If caught early, you can slide
the ring up the piping and
expand as described in the
previous bullet point.
More than the recommended
number of expansions are
needed to make a connection
• Ensure the head is hand-
tightened to the expander tool.
• Examine the segment fingers
for damage.
• Be sure to completely cycle
the tool on each expansion
(i.e., close the manual tool
handle or release the trigger).
Cold-weather expansions
• Uponor recommends the use
of the Milwaukee M12 FUEL
ProPEX expansion tool with
RAPID SEAL™ heads for cold-
weather installation of

Uponor piping systems.
• Temperatures affect the time
required for the piping and ring
to shrink onto the fitting. The
colder the temperature, the
slower the contraction time.
• Warming ProPEX fittings
and ProPEX rings reduces
contraction time. Put fittings
and rings in your pockets
prior to installation to keep
them warm.
• Fewer expansions are
necessary in temperatures
below 40ºF (4.4ºC).

Note: Do not use a heat gun on EP fittings to speed up the
contraction time as this could result in damage to the fitting.
