53N87 - Weldcraft 53N87 Large Diameter Alumina Gas Lens Nozzle #12 (10-Pack)

Weldcraft 53N87 Large Diameter Alumina Gas Lens Nozzle #12

The Weldcraft 53N87 is a premium Alumina Gas Lens Nozzle designed to elevate the performance of your TIG welding operations. Manufactured by Miller Electric under the renowned Weldcraft brand, this nozzle is engineered for professionals who demand precision, durability, and superior shielding gas coverage. This specific model is a size #12 cup, boasting a 3/4-inch (19mm) bore diameter, making it an excellent choice for applications requiring a broad umbrella of shielding gas to protect the weld pool from atmospheric contamination.

Constructed from high-impact alumina ceramic, the 53N87 is built to withstand the rigorous thermal cycles associated with high-amperage TIG welding. Alumina is chosen for its exceptional thermal conductivity and resistance to thermal shock, ensuring that the nozzle maintains its structural integrity even during prolonged welding sessions ranging from 125 to 500 amps. Furthermore, the material naturally resists spatter buildup, reducing downtime for cleaning and maintenance.

This nozzle is specifically designed to work with Large Diameter Gas Lenses. Gas lenses are critical for improving weld quality as they replace the standard turbulence of a collet body with a coherent, laminar flow of gas. This laminar flow allows the welder to extend the tungsten electrode further past the cup—often up to an inch or more—without losing gas coverage. This feature is indispensable when welding in deep corners, fillets, or obstructed areas where visibility is limited. The 53N87 fits a wide array of popular TIG torches, including the 9, 17, 18, 20, 26, and 27 series, provided they are equipped with the appropriate large diameter gas lens collet body.

Sold in a convenient package of 10, the Weldcraft 53N87 ensures you have a reliable supply of consumables on hand for critical fabrication tasks. Whether you are working on aerospace components, motorsports fabrication, or sanitary stainless steel piping, the superior coverage provided by this #12 cup helps prevent oxidation and porosity, leading to cleaner, stronger, and more aesthetically pleasing welds.
