105Z27 - ESAB .020" Collet Body for HW-9/HW-20/HW-90 Torches (Pack of 2)

Precision TIG Components for ESAB Torches

The ESAB 105Z27 Collet Body is a critical consumable designed for precision TIG welding applications requiring the smallest standard tungsten diameter. Engineered to fit 0.020-inch (0.5mm) tungsten electrodes, this collet body is compatible with a range of ESAB torches, including the HW-9, HW-20, and HW-90 series. As a genuine OEM part, it guarantees the dimensional accuracy required for high-quality welding in aerospace, electronics, and fine instrumentation fabrication.

Manufactured from high-grade copper alloy, the 105Z27 offers excellent thermal and electrical conductivity. This ensures that welding current is transferred efficiently from the torch power cable to the tungsten electrode, minimizing resistance and heat buildup within the torch head. The collet body also plays a vital role in gas management; its internal geometry helps align the collet and tungsten while directing shielding gas flow towards the nozzle, ensuring adequate coverage of the weld pool.

This product is supplied in a pack of 2, allowing professional fabricators to maintain stock of essential consumables. Regular inspection and replacement of collet bodies are recommended to prevent thread degradation and poor arc performance caused by wear or overheating. Whether you are repairing a legacy HW-90 torch or outfitting a standard HW-20 water-cooled setup, the ESAB 105Z27 delivers the reliability expected from a world leader in welding technology.
