SUPER STARS - TORQUE WRENCH 29 MM FOR DUTCH NUTS 5/8", 75 Nm

The Super Stars torque wrench 29 mm is a professional tool designed for precise tightening of flare nuts on 5/8” diameter copper pipes when installing and servicing air conditioning and refrigeration systems. The wrench has a factory-set fixed tightening torque of 75 Nm, so additional setting, adjustment or reading of the measuring scale is not required. Simply place the wrench on the nut and tighten until the mechanism signals that the prescribed tightening torque has been reached. This design simplifies installation and reduces the possibility of tightening errors. The appropriate tightening torque helps prevent refrigerant leakage due to undertightened joints and damage to the cone or nut due to excessive force. Due to its compact design and ratchet mechanism, the ST-02-L enables efficient work even in confined spaces, along walls, inside air conditioning housings and in other difficult-to-reach places.

FIXED TIGHTENING TORQUE FOR PRECISE TIGHTENING

The torque wrench is specially adapted to flare nuts used on 5/8" diameter copper pipes. The factory-set tightening torque of 75 Nm enables repeatable and precise tightening without manual adjustment. The mechanism clearly signals when the prescribed tightening force is reached. This reduces the risk of incorrect tightening and improves the reliability of pipe joints when installing air conditioners.

RATCHET MECHANISM FOR WORKING IN CONFINED SPACES

The built-in ratchet mechanism allows for easier tightening even where access with a conventional torque wrench is difficult. The compact design ensures good maneuverability and practical use when installing and servicing air conditioning and refrigeration systems.
