SUPER STARS - TORQUE WRENCH 17 MM FOR DUTCH NUTS 1/4", 18 Nm

The Super Stars torque wrench 17 mm is a professional tool designed for correct and precise tightening of flare nuts on 1/4” diameter copper pipes when installing and servicing air conditioning and refrigeration systems. The wrench has a factory-set fixed tightening torque of 18 Nm, so additional setting, adjustment or reading of the measuring scale is not required. Simply place the tool on the nut and tighten until the mechanism signals that the prescribed torque has been reached. The fixed tightening torque value reduces the possibility of under- or over-tightening, which helps prevent damage to the cone and subsequent refrigerant leakage. Due to its compact design and ratchet mechanism, the ST-02-L allows easy work even in confined spaces, along walls, under the housings of indoor and outdoor units and in other difficult-to-reach places.

FIXED TIGHTENING TORQUE FOR PRECISE ASSEMBLY

The torque wrench is specially adapted to standard flare nuts used on 1/4" diameter copper pipes. The factory-set torque of 18 Nm ensures repeatable tightening without the need for manual adjustment. When the correct tightening force is reached, the mechanism clearly signals correct tightening. This solution allows for faster work and reduces the risk of damage to pipe connections due to excessive force.

RATCHET MECHANISM AND COMPACT DESIGN

The integrated ratchet mechanism allows for efficient use in confined work spaces where moving a conventional wrench is difficult. The compact design ensures good maneuverability and practical use when installing and servicing air conditioning and refrigeration systems.
