The ATC20126-A Injector Setting Torque Wrench is a precision T-handed Torque wrench calibrated to 6 in-lb torque, designed for setting injector preload on Cummins diesel engines (OEM Cummins part number 3376592).
Used in injection system assembly and maintenance, this torque wrench applies the correct preload to injector setting to ensure reliable sealing, injector start pressure consistency, and longevity of the injector assembly. It’s especially important during rebuilds, injector swapouts, or engine overhauls where precise torque control is critical.
Built for durability and repeatability, the ATC20126-A helps prevent over- or under-torquing, which can lead to injector leaks, injector seat damage, or premature failure.
