3. Make a perpendicular cut to PEX tubing to the needed
length. Use ONLY cutters designed for PEX tubing.
4. Slide the PEX Ring
11
over the end of the PEX
tubing
12
until it sits properly against the ring stop. If
the PEX ring does not have a stop, leave an over-hang of
no more than 1/16" (1.6 mm) (Fig. G)

. The expander head will
begin to expand, retract, and rotateslightly.
NOTE: Hold the ring and tubing so they do not rotate with
thehead.

PEX Ring Size Recommended Number of Expansions

1/2" 7-8
5/8" 9-10
3/4" 11-12
1" 17-18
NOTE: The number of expansions needed may vary
depending on temperature or user technique. To avoid over-
expanding the PEX tubing, do not keep tool in the expanded
position with PEX tubing inplace.
7. After achieving the recommended number of expansions,
remove the tubing when the expander cone
2
segments
are retracted and release the trigger switch
4
. DO NOT
expand the PEX tubing beyond the tool's capacity of
1inch.
8. Wipe off the excess grease from inside the PEXtubing.
9. Slide the PEX tubing over the fitting until it is flush with
the fitting shoulder. The connection may be tight. If you
are unable to slide the PEX tubing over the fitting, remove
the fitting from the PEX tubing and re-expand until you
can secure a properfit.
NOTE: The PEX tubing should fit tightly against the fitting
shoulder. If there is more than a 1/16" (1.6 mm) gap between
the PEX tubing and the shoulder, cut 2" (50 mm) off the end
of the PEX tubing and restart procedure with a new PEXRing.
Making 3/8" PEX Tubing Connections
(Fig. A, G)
The thicker 3/8" PEX rings will not fit over 3/8" PEX tubing
without first expanding each end of the PEXring.
1. Insert the expander head
1
into the PEX ring
11
.
2. Squeeze the trigger switch
4
and allow the expander
head to exapand the PEX ringonce.
3. Remove the PEX ring and repeat steps 1 and 2 for the
other end of the PEXring.
4. IMMEDIATELY slide the PEX ring onto the end of the PEX
tubing
12
leaving an over-hang of no more than 1/16"
(1.6 mm)(Fig.G).
NOTE: 3/8" PEX rings will shrink faster than other size
PEXrings.
5. Continue with the steps outlined in Creating a PEX
Tubing Connection to complete yourconnection.
Cold weather use
Use of your PEX expander in colder temperatures
(<40°F/4°C) requires a longer contraction time and less
expansions. Attempting to make PEX connections in
extreme temperatures (<5 °F/-15 °C) is notrecommended.
Expansion Markings (Fig. I)
CAUTION: Incorrect expansion of the PEX tubing can
create deep grooves in the material which could result
in faulty connections and risk of propertydamage.
Examples of correct and incorrect markings on the inside of
the PEX tubing are shown in Fig. I. Incorrect markings could
indicate the head is not rotating properly, or the tubing is
rotating with thehead.
