53N59 - Weldcraft 53N59 Alumina Gas Lens Nozzle #5 (5/16") - 10 Pack

High-Performance Alumina Gas Lens Nozzle for Precision TIG Welding

The Weldcraft 53N59 Alumina Gas Lens Nozzle is a critical component for industrial TIG welding operations requiring superior shielding gas coverage and equipment durability. Manufactured from high-grade alumina ceramic, this nozzle is engineered to withstand significant thermal shock and high-impact environments common in heavy fabrication and manufacturing settings. The #5 size, featuring a 5/16-inch (8mm) orifice, provides a focused column of shielding gas, essential for protecting the weld pool from atmospheric contamination.

This nozzle is specifically designed to interface with gas lens collet bodies. Unlike standard collet bodies that create turbulent gas flow, gas lenses utilize a mesh screen to organize the shielding gas into a laminar flow pattern. The 53N59 nozzle accommodates this improved flow, allowing the welder to extend the tungsten electrode further—up to one inch in some applications—without losing gas coverage. This feature is particularly advantageous when welding in confined spaces or complex geometries where visibility and access are limited.

Compatibility is a key strength of the 53N59. It is designed to fit a wide range of air-cooled and water-cooled TIG torches, including the 9, 20, 22, 24, and 25 series. This versatility makes it a staple inventory item for maintenance, repair, and operations (MRO) departments managing diverse welding equipment. The alumina material also exhibits low thermal conductivity, helping to insulate the torch head from the intense heat of the arc, thereby prolonging the lifespan of internal torch components.

Supplied in a pack of 10, these nozzles ensure that welding stations remain operational with minimal downtime. Whether used for precision aerospace applications or general industrial fabrication, the Weldcraft 53N59 delivers consistent performance, reducing the likelihood of weld defects such as porosity and oxidation. Its resistance to spatter buildup further reduces maintenance time, allowing operators to focus on arc quality and productivity.
