Double Squeeze™ PE Squeeze Tools
PES4DB/PES4DMB User Manual
PRIOR TO USE
• Only trained personnel should use this tool. Read and
understand instructions before operating. A mock squeeze-
off is recommended for users not familiar with the squeeze
procedure and the anatomy of the tool.
• Verify all parts are clean and free of debris that
may hinder operation.
• REED PE Squeeze Tools are to be used on
polyethylene (PE) pipe only.
• Manual REED Squeeze Tools must be operated by
hand and without the use of power tools.
• The use of additional leverage (i.e. cheater bars) is not
needed. The tool was designed to give adequate leverage
with the incorporated slide handle.
TOOL OPERATION REMINDERS
• When satisfactory ow control cannot be obtained with one
tool, REED recommends a double squeeze-off. This means
using two squeeze tools in series.
• Be aware of the recommended squeeze/release rates to
avoid pipe damage (2 inches/min. [51 mm/min.] squeeze
and ½ inch/min. [13 mm/min.] release). Rates should be
slowed further in colder weather. Consult the local utility for
recommendations regarding squeeze and release rates.
• A squeeze should be performed a minimum of 12 inches
(305 mm) or 3 times the pipe diameter (whichever is greater)
from ttings, fusions, or previously squeezed pipe. Refer to
ASTM standard designation F1041-02 for more information.
WARNING
Cold temperatures can affect the pipe integrity during the
squeeze. Squeeze and releases rates need to be slowed in
temperatures below 50 F [10°C]. Cold temperatures can affect
the squeeze (below 50 F [10°C]) and result in a less than
desirable ow control. Give adequate time for the pipe to relax
during the squeeze (5-15+ minutes) and perform a double
squeeze-off if necessary.

SQUEEZE PROCEDURE
WARNING
Avoid binding the tool. Keep the squeeze bars parallel to each
other to avoid tool damage. Check bottom bar pockets are
clear of debris to ensure proper closure of the tool.
Squeezing PE Pipe
1. Raise the top bar using the feed screw and sliding handle for
the pipe size you are squeezing.
2. Assemble the helper handle where needed.
3. Follow your company policy concerning static electric
discharge at this stage of the procedure.
NOTE: REED strongly recommends use of the PEGR7
Static Grounding Device #04621 with PE Squeeze Tools.
The threaded connection for the PEGR7 is on the head. Use
a grounding accessory as a precaution against static build-up.
Dissipate the charge and minimize the possibility of ignition.
Additional information and precautions on static electricity is
available in the PPI Handbook of Polyethylene Pipe.
4. Lift and swing out bottom bar and mount onto the pipe. Close
the bottom bar, ensuring the rod nuts are set securely in the
bottom bar pockets.
CAUTION
Center the pipe along the width of the bars and square the
pipe relative to the tie rods.
5. Select both pipe stops based on pipe diameter and SDR.
Position both pipe stops so that the corresponding at is
facing the bottom bar. Stops must match one another.
6. Turn the feed screw to squeeze the pipe. Momentary pauses
will allow the pipe to relax and will result in less user fatigue.
Recommended squeeze rate to avoid pipe damage is 2
inches/min. [51 mm/min] maximum. Squeeze until pipe stops
are contacted or feed screw will no longer turn and there is
satisfactory ow control.
CAUTION
Stop squeezing when pipe stops contact bottom bar, further
squeezing will cause tool damage.
NOTE: Pipe stops don’t need to contact bottom bar to
satisfactorily control ow.
Releasing PE Pipe
1. Slowly and carefully release the pipe by unscrewing the
feed screw while carefully watching the squeeze bars for
movement. The recommended release rate to avoid pipe
damage is ½ inch/min. [13 mm/min] maximum.
2. When the squeeze bars, due to internal pipe pressure,
no longer assist the operator in the release, unscrew and
remove the tool from the pipe.
3. Rerounding the pipe can optionally be done by rotating the
tool 45°-90° and applying enough force to round pipe.
4. Inspect squeezed section for damage before covering.
Procedures should be followed that will prevent the same
area from being squeezed-off more than once.
Care and Maintenance
1. Wipe down and clean the tool.
2. Store the tool in a dry place.
3. Keep the feed screw and nut clean and free of debris. Failure
to perform this maintenance will make it more difcult for
the operator to achieve the force necessary for a successful
shutoff.
4. Periodically grease the nut and bearing cavity.
(2 grease ttings are mounted on the tool).
