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 pipe setting on the rotating
sleeve 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-of f Tools.

SAFETY INSTRUCTIONS

SAVE THESE FOR FUTURE REFERENCE

Static Electricity Safety

Use a proper grounding rod at all times to insure personal safety.
PE pipe is a relatively low conductor of electricity. As a result PE

pipe does build up a static charge when it is in gas service due to
the gas flow on the inside of the pipe. During squeeze-off a larger amount of static
charge builds up.

In addition to the potential for pipe damage due to static discharge, the build up
of a static charge represents an ignition source. Timberline Tool recommends
that you follow all of your company grounding techniques and that all personnel
involved in squeeze-off operations receive training on those grounding procedures
so that they understand the hazards involved.

Workplace Safety

Prior to using any squeeze-off tool, consult ASTM Standards F1041­02, F1563-01 and F1734-03.

Always follow applicable company and OSHA safety procedures.

Observe pipe manufacturers’ recommendations and precautions for squeeze-off of
polyethylene pipe, exercising particular caution when leaking gas is present.

Safety first. T imberline squeeze-off tools must be used by qualified, trained per-
sonnel only and must never be left on the pipe unattended. Refer to pipe manufac­turers’ recommendations for locating squeeze-off distances from fittings and joints.

Personal Safety

Stay Alert, watch what you are doing, and do not use tools while

tired or under the influence of narcotics, alcohol, or medication.

Use proper clothing, eye protection, and safety equipment when
using squeeze-tools.

A moment of inattention while operating squeeze-of f tools may result in personal injury.
Store idle tools out of reach of children and other untrained persons.
