53N88 - ESAB 53N88 #10 Large Gas Lens Alumina Cup (Pack of 10)

Premium Shielding for Precision TIG Welding

The ESAB 53N88 Alumina Large Gas Lens Nozzle is a critical consumable for professional TIG welders demanding superior shielding gas coverage and weld pool visibility. Sized as a #10 cup with a 5/8-inch (15.8 mm) orifice, this nozzle is specifically engineered to interface with large gas lens collet bodies. Unlike standard collet bodies that create turbulent gas flow, the large gas lens system utilizes a multi-layer screen to organize the shielding gas into a coherent, laminar column. This laminar flow is essential when welding reactive metals like stainless steel, titanium, and aluminum, where atmospheric contamination can compromise the structural integrity and aesthetic appearance of the weld.

Manufactured from high-grade alumina ceramic, the 53N88 offers exceptional thermal shock resistance and electrical insulation. This robust material composition ensures the nozzle can withstand the intense heat cycles of high-amperage welding (rated for applications up to 500 amps) without cracking or degrading prematurely. The ceramic's smooth finish also helps resist spatter adhesion, making post-weld cleanup easier and extending the consumable's service life. With a standard length of 1-7/8 inches, it provides a familiar form factor that balances reach with durability.

Versatility is a key advantage of the 53N88. While primarily designed for the 17, 18, and 26 series "large" torches, it is also compatible with 9 and 20 series torches when equipped with the appropriate large gas lens insulator and collet body. This cross-compatibility allows fabrication shops to standardize their consumable inventory across different torch models. The wider 5/8-inch bore is particularly beneficial for "walking the cup" techniques on pipe and heavy plate, providing a stable base and broad gas envelope. Supplied in a convenient pack of 10, these nozzles ensure your welding operations remain uninterrupted and productive.

Key Technical Benefits

• Laminar Flow: Works with gas lenses to push gas further, allowing for extended tungsten stick-out to reach into deep corners and fillets.
• Thermal Durability: Alumina composition resists heat fracture even during extended duty cycles.
• Broad Compatibility: Fits a wide range of air-cooled and water-cooled torches commonly found in industrial environments.
