ESCO Flare nut torque wrench EA723BK series

If the flare nut wrench is not tightened correctly, it can cause damage to the flare due to insufficient or excessive tightening, resulting in refrigerant leakage. Using a torque wrench allows for easy and accurate tightening. When tightened to the specified torque value, you will hear a click and the neck will break. Releasing the force will return it to its original position. *About torque wrenches: When using, apply the torque wrench perpendicular to the flare nut surface. If applied diagonally, the torque wrench may slip or the neck may not break at the appropriate torque value.
