Making ProPEX Connections
with the ProPEX Hand
Expander Tool
Without Auto Rotation
3. When using a ProPEX Hand Expander Tool
without the ProPEX Auto Rotation Adapter,
brace the free handle of the tool against your
hip, or place one hand on each handle. Fully
separate the handles and slide the expander
head into the tubing until it stops. Full
expansions are necessary to make a proper
connection. Bring the handles together to
expand. Separate the handles, remove the
head from the tubing, rotate it
1
⁄8 turn and
slide the head back into the tubing. Continue
expanding and rotating until the tubing and
ring are snug against the shoulder on the
expander head. See Table 3-1 on page 13 for
the recommended number of expansions for
each tubing size.
Important! Rotating the tool between
expansions will provide smooth, even
expansion of the tubing. Failure to rotate the
tool will cause deep grooves in the tubing
which can result in potential leak paths.

1. Square cut the PEX tubing
perpendicular to the length of
the tubing. Remove all excess
material or burrs that might
affect the fitting connection.
2. Slide the ProPEX Ring over
the end of the tubing until it
reaches the stop edge. If using
a ProPEX Ring without a stop
edge, extend the ring over the
end of the tubing no more than
1
⁄16" (1mm).
Important! If making a
3
⁄8"
ProPEX Connection, you must
first expand each side of the
ring before placing it on the
tubing. Refer to the “Making
3
⁄8" ProPEX Connections”
instructions on page 20 for
further information.
