Proper ProPEX 200 Battery Expander Tool and Head
Maintenance
The ProPEX 200 Battery Expander Tool comes with a 2" H-series Expander Head.
Optional expander heads come in sizes ranging from 3⁄8"to 11⁄2". All heads contain
six segment fingers, one attachment ring and one spring. It is very important to
keep the head on the tool or in the tool case at all times as dirt and other debris
can affect the connection process.
1. Remove and clean the segment fingers as needed. Remove the segments
from the attachment ring by pushing the segment finger down toward
the opening in the ring. Once the first segment is removed, the rest
follow easily.
2. Place the segments on a flat surface with the ridges facing up. The
fingers should lay flat without any curve in the middle. If the segments
are bent, replace the head immediately.
3. To reassemble, replace the segment fingers one at a time to the
attachment ring by sliding the grooved portion of the segment fingers
over the spring in the attachment ring. The narrow end of the segment
fingers points away from the solid side of the attachment ring. Hold
these segment fingers in placewith your thumb as the remaining
segment fingers are inserted.
4. Once the expander head is cleaned and reassembled, use a clean,
lint-free cloth to apply a light coat of Molykote g-n plus lubricant
to the expander cone prior to making any ProPEX connections.
5. Apply the lubricant daily if used regularly.
6. Keep all other parts of the tool free from lubricant.
Note: Failure to properly lubricate the tool may result in improper connections.
Caution: Excessive lubrication may result in improper connections. Only
use a small amount of lubricant to keep the tool working properly.
7. Monthly,soak the heads in a degreasing agent to remove any grease from
between the segments. Clean the cone using a clean, drycloth.
8. Store the tool and expander heads in the case. Store the tool with an
expansion head in place to protect the cone.
9. Store the tool in a drylocation toprevent rust.
Refilling Hydraulic Oil Reservoir
Check the level of hydraulic oil in the reservoir daily. The oil level should reach the
top threads of the filling hole. If the oil level is low, refer to the following
instructions to refill the reservoir.
1. Ensure the tool is on a flat, stable surface.
2. Unscrew the cap from the filling hole on the reservoir.
3. Fill the tank with Texaco AW 32 Hydraulic Oil or equivalent to the top
threads of the filling hole.
4. Replace the cap.
Note: Due to oil expansion from temperature changes, oil may overflow
when opening the reservoir cap. This is normal.

Section 5 – Making ProPEX
Connections
Tools Needed
• ProPEX 200 Battery Expander Tool
• Properly sized expander head, hand-tightened onto the tool
• Tubing cutter designed for PEX tubing
11
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. Extend the end of
the ring over the end of the tubing
no more than 1⁄16"(1mm).
3. Slide the expander head intothe
tubing until it stops. Full
expansions are necessary to make
a proper connection. Press the
trigger to expand. Release the
trigger, remove the head from the
tubing and rotate it 1⁄8turn. Slide
the tool head intothe tubing in
the newly rotated position and
expand again.
Important: Rotating the tool 1⁄8
turn expands the tubing smoothly
and evenly. If the head is not
repositioned after each expansion,
the segments on the tool head
may cause deep grooves in the
tubing, resulting in potential
leak paths.
max 1⁄16"

12
Note: It is not necessary to rotate the tool in only one direction. Alternating
the turning direction will ease expansion in confined spaces. The photos above
show enlarged views inside expanded tubing.
4. Repeat the expansion process until
the tubing and ring aresnug against
the shoulder on the expander head.
See Table 4 for the recommended
number of expansions for each
tubing size.
Note: The ‘’H’’ in the table refers to the H-series expander heads, which are
only used with the ProPEX BatteryExpander Tools. Only use the 2" H-series
Expander Head on the ProPEX 200 Battery Expander Tool.
5. Immediately remove the ProPEX 200
BatteryExpander Tool. As you slide
the tubing over the fitting, you
should feel some resistance. If the
tubing reaches the shoulder of the
fitting without any resistance, the
tubing may be over-expanded and
may requireadditional time tofully
shrink over the fitting. The tubing
and ProPEX Ring should seat against
the shoulder of the fitting for a
proper connection.

Table 4: Recommended Expansions

Important Tips for a Proper ProPEX Connection
• If the fitting does not slide into the tubing all the way to the stop,
immediately remove it from the tubing and expand the tubing one
final time.
Note: To avoid over-expanding the tubing, do not hold the tubing in
the expanded position.
•Table 4 lists the recommended number of expansions for the various
sizes of PEX tubing. Experience, technique and weather conditions
influence the actual number of expansions. Fewer expansions may be
necessary under certain conditions. The correct number of expansions
is the amount necessary for the tubing and the shoulder of the fitting
to fit snugly together.
• A good connection is when the ProPEX Ring rests snugly against
the stop of the ProPEX fitting shoulder. If there is more than 1⁄16"
between the ring and the shoulder of the fitting, square-cut the
tubing 2" away from the fitting, and make another connection
using a new ProPEX Ring.
Making 3⁄8"ProPEX Connections
The 3⁄8"ProPEX Ring is smaller and thicker than the ProPEX rings used for other
tubing sizes. The 3⁄8"ProPEX Ring must be expanded once on each side to
properly fit over the tubing. Expansion of the ProPEX Ring is only necessary for
3⁄8"Wirsbo AQUAPEX.
1. Square-cut the 3⁄8" Wirsbo AQUAPEX tubing perpendicular to the
length of the tubing.
2. Expand each side of the 3⁄8" ProPEX Ring with the ProPEX 200 Battery
Expander Tool once.
3. Slide the expanded 3⁄8" ProPEX Ring over the end of the tubing.
Extend the end of the ring over the end of the tubing no more than
1⁄16" (1mm).
Once the 3⁄8"ProPEX Ring is properly expanded and on the tubing, refer to
Steps 3-5 on pages 11 and 12 for further instruction.
Important Tips for a Proper 3⁄8"ProPEX Connection
• When the temperature is above 40°F (5°C), ProPEX connections to 3⁄8"
Wirsbo AQUAPEX tubing require four to five expansions. When the
temperature is below 40°F (5°C), only four expansions are necessary.
• The thicker ProPEX Ring used for 3⁄8"ProPEX connections shrinks over
the fitting faster than other size rings.
Disconnecting a ProPEX Brass Fitting
ProPEX brass fittings aremanufactured connections and can be concealed in
walls, ceilings and floors. However, when necessary, ProPEX Brass Fittings can
be disconnected. To disconnect a brass fitting:
1. Make sure the system is not pressurized.
2. Use a heat gun toheat one side of the ProPEX Ring. When the ring
13

14
is clear, use a utility knife to carefully cut through the ring. Care
should be taken to cut only the ring and not the tubing. This will
protect the fitting from becoming gouged by the knife. Remove the
ProPEX Ring from the tubing with pliers or another tool to avoid
touching the hot ring.
Note: Do not gouge the fitting when cutting the ProPEX Ring.
Nicks and gouges in the fitting may result in leaks. If nicked,
discard the fitting.
3. When the ProPEX Ring is removed, apply heat directly around the
fitting and tubing connection. Gently work the tubing back and forth
while pulling slightly away from the fitting until the tubing separates
from the fitting.
4. When the tubing is removed from the fitting, square cut the tubing
2" (minimum) from the end of the tubing.
5. Use a new ProPEX Ring and follow the steps to make a new ProPEX
connection. Allow the fitting to cool before attempting to make
another connection.
ProPEX Connection Troubleshooting Guide
Trouble-free ProPEX installations begin with a ProPEX 200 Battery Expander
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. The
following troubleshooting guide is designed toassist with problems in the field.
Fittings Do Not Seal
For fittings that do not seal, follow the steps below.
1. Ensure the expander head is securely hand-tightened onto the tool.
2. Makesure the segment fingers are not bent. If the head does not
completely close when the electro-hydraulic drive unit is fully
retracted, replace the head.
3. Remove any excess grease on the segment fingers.
4. Examine the fitting for damage. Nicks and gouges on the fitting will
cause the fitting toleak.
5. Ensure the internal driver is not damaged or bent.
6. Make sure the last expansion is not held in the expanded position for
more than three seconds before the fitting is inserted. The longer the
tubing and ring are held in the expanded position, the greater chance
for a leak.
7. Be sure to rotate the tool 1⁄8turn after each expansion.
Expansion is Difficult
If it is difficult tomakean expansion, check toensure the internal cone is
properly greased with Uponor-recommended Molykote G-n plus.
