10N49L - Weldcraft Long Alumina TIG Cup #5L (5/16") for 17/18/26 Torches - 10 Pack

Precision TIG Welding with Extended Reach

The Weldcraft 10N49L Long Alumina Nozzle is an essential consumable for professional TIG welders who require access to difficult joints and confined spaces. Manufactured from high-grade alumina ceramic, this nozzle is engineered to withstand the intense heat and thermal cycling inherent in Gas Tungsten Arc Welding (GTAW). Unlike standard length cups, the 10N49L features an elongated body that allows the welder to extend the tungsten electrode further while maintaining adequate gas coverage, making it perfect for welding inside corners, pipe roots, and complex manifold assemblies.

This specific nozzle is a size #5L, featuring a 5/16-inch (8mm) orifice. This diameter provides a focused stream of shielding gas, which is critical when welding with extended stick-out to prevent atmospheric contamination of the weld pool. The ceramic material offers excellent electrical insulation and high impact resistance, reducing the frequency of replacements due to cracking or chipping during use. It is designed to resist spatter buildup, ensuring a smooth gas flow and consistent arc stability throughout the welding process.

Compatibility is key in industrial environments, and the 10N49L is designed to fit the industry-standard 3-Series TIG torches. This includes the air-cooled 17 and 26 series torches, as well as the water-cooled 18 series torches. Whether you are using a Miller, Lincoln, or generic torch body, if it adheres to the standard 17/18/26 form factor, this nozzle will thread on securely. Sold in a pack of 10, this product ensures that fabrication shops and maintenance departments have a ready supply of high-quality consumables to keep downtime to a minimum.

By choosing genuine Weldcraft parts, you are investing in consistency. Cheap generic ceramics often suffer from poor threading or inconsistent wall thickness, which can lead to uneven heat dissipation and premature failure. The Weldcraft 10N49L delivers the reliability professional welders expect, ensuring that every weld meets the required specifications.
