02 Feb Mustang Squeeze Tool Lifespan

MUSTANG MFG. TECHNICAL BULLETIN 2024-16
Mustang Mfg. has been asked recently by several utilities “What is the realistic “lifespan” of our PE pipe squeeze tool”? This question arises because of the thousands of Mustang PE squeeze tools still in service today with some of them being quite old. Some background on tool design and inspection practices are listed below to help identify Mustang tools that have met their maximum life.
Mustang Mfg., prior to that Melfred Welding, has been designing and building PE pipe squeeze tools since 1968. The original tools were designed to be used on the pipe of that time. As the pipe resin and pipe manufacturing processes changed, the requirements placed on the squeeze tool changed. The pipe produced today often requires more force to satisfactorily squeeze off as compared to the pipe of the earlier generations. Mustang PE tools were updated and redesigned in early 2002 to meet the new requirements.
Compared to the earlier pipe, more torque is often required, on mechanically operated tools, to achieve a satisfactory squeeze off. The handle provided with each mechanical squeeze tool is sized to provide adequate torque to squeeze the pipe within the size range of the particular tool. It is important to USE THE HANDLE PROVIDED WITH THE TOOL. The use of a “cheater bar” or pipe wrench risks over-stressing the frame.
The current design Mustang Model DBS-20C and DBS-24C were introduced in early 2002. These tools are identical in operation to the previous generations but feature a greatly strengthened frame design to better withstand the severe abuse that they may be subjected to. This is not to say that the previous generation tools were not strong enough, but the continual use and the use of non-approved “torque applicators” over many years can induce stresses not originally anticipated.
Mustang is therefore recommending that all 2″ squeeze tools manufactured prior to 2002 be closely examined for signs of over-stress and/or be retired from service. The included diagrams and photos will help identify the later design tools and provide guidelines as to what to look for in inspecting the tools for over-stress.
There are many hundreds of the original design tools still in service and inspection of their condition is a good practice because of the larger forces required with the current PE pipe materials. The close inspection and evaluation of all your tools’ condition will allow you to get the maximum “lifespan” of your Mustang tools and ensure the safety of the operator.
Mustang has always had a reputation for providing the safest and most reliable tools on the market and that will never be compromised.
