INTRODUCTION
Timberline squeeze-off tools are designed to temporarily stop the pressurized flow of
liquid or gas in polyethylene (PE) pipe.
Squeeze-off is a technique used to control the flow of gas or liquid in polyethylene
pipe by compressing the pipe between parallel bars until the inside surfaces make
contact. The flexibility and toughness of most polyethylene pipes allow the pipe to
recover from a properly made squeeze-off without a measurable loss in service life.
Squeeze-off is useful for making installation tie-ins and emergency repairs.
Timberline squeeze-off tools are made from high strength aluminum for superior
durability and will not bend or break under normal use. However, care must be taken
to ensure that the pipe is free of foreign material and the slap on jaw matches the
diameter and SDR of the pipe to be squeezed.
Please read the following suggested procedure for squeezing off polyethylene plastic
pipe using Timberline Squeeze-off Tools.
GENERAL SAFETY RULES
For all Tools
READ and UNDERSTAND all instructions. Failure to follow all instructions listed
below may result in serious personal injury and/or damage to the tool.
The following ASTM standards provide guidance and requirements for squeeze-off
tools, operating procedures, and qualification procedures.
• ASTM F1041, “Standard Guide for Squeeze-off of Polyolefin Gas Pressure
Pipe and Tubing”
• ASTM F1563, “Standard Specification for Tools to Squeeze-Off Polyethylene
(PE) Gas Pipe or Tubing”
• ASTM F1734, “Standard Practice for Qualification of a Combination of Squeeze
Tool, Pipe, and Squeeze-Off Procedures toAvoid Long-Term Damage in Poly-
ethylene (PE) Gas Pipe”
