Safety Considerations
Pressure control situations requiring squeeze-off may involve
working in the vicinity of escaping gas. Consider the possibility and
potential hazard of static electricity and observe safety precautions.
Precautions can be taken to dissipate the charge, and minimize
the possibility of an ignition. This will maximize the personal safety
of the crew. These precautions should be followed as a minimum,
conditions may require additional measures.
• To provide dissipation for static charge, wet down surfaces with
conductive fluids and/or apply conductive films or fabrics to the
pipe. Keep precautions in place until procedures are complete.
• Ground all tools.
• Periodically verify that continuity is maintained from ground
probe to tool.*
Check the squeeze-off tool prior to use to assure it is the cor-
rect size; is properly functioning; and is properly adjusted for the
squeeze-off to be done.
* Consider using Reed’s Static Grounding Device #04621.
Additional information on static electricity is available in the PPI Handbook
of Polyethylene Pipe 2nd Edition.

PES1 Operating Instructions
Capacity: ½” to 1”
1. Follow safety procedures.
2. Determine pipe/tube size and wall thickness. Set
stops for over-squeeze protection.
3. Insert ground probe into moist soil (for gas
applications).
4. Raise the Top Crimp Bar by turning the Feed Screw.
5. Center the squeeze-off tool on and square to pipe.
6. Turn the feed screw to compress the pipe at a
slow rate with momentary pauses to allow stress
relaxation in the pipe to occur. This is particularly
important in cold weather.
7. Squeeze the pipe until flow is controlled or top bar
contacts the stops.
Tool Removal
1. Maintain a release rate of ½ inch per minute to
prevent damage to pipe as recommended by
ASTM F1041.
2. Rotate the tool 90° and re-apply force to re-round
pipe.
3. Inspect squeezed section for damage before
covering. Procedures should be followed that
prevent squeezing the same area of the pipe again.
