THE STINGER® and 1FR™Penetrating Fluid BY FIRSTPOWER

The STINGER® tools and 1FR™ Penetrating Fluid, conceived, designed and manufactured by FirstPower Group LLC. The result of lengthy investigation into the difficulties associated with switching operations, seeking to understand how productivity is impacted, what is the cost of lost productivity and what solutions were available to address these problems. The findings showed most chemicals and tools marketed to stuck switches did not work. This led FirstPower to create the STINGER® and 1FR™ Penetrating Fluid.
