10N49 - 10N49 Alumina TIG Cup #5 (5/16") - Pack of 10

Reliable TIG Welding Consumables for Industrial Applications

The Generic 10N49 Alumina Nozzle Cup is an essential consumable for professional TIG welding operations. Designed to fit the widely used 3-series torches—specifically the 17, 18, and 26 models—this nozzle provides the consistency and durability required for high-volume fabrication. Manufactured from high-grade alumina ceramic, these cups are engineered to withstand significant thermal shock and resist the adhesion of weld splatter, ensuring a longer service life and reduced downtime for replacements.

This pack of 10 nozzles features the standard #5 size, offering a 5/16-inch (8mm) orifice. This size is ideal for general-purpose welding applications where a focused gas stream is necessary to protect the weld pool from atmospheric contamination. Whether you are welding stainless steel, aluminum, or mild steel, maintaining a clean and stable shield gas flow is critical for weld quality. These generic replacements offer a cost-effective solution for MRO departments and fabrication shops looking to maintain inventory levels without compromising on the quality of their torch setups.

Compatibility is key in industrial environments. These 10N49 nozzles are direct replacements for major brands such as Weldcraft, Miller, and CK Worldwide. They thread easily onto standard collet bodies and gas lens setups, providing a secure fit that prevents gas leakage and turbulence. By choosing this 10-pack, facility managers can ensure their welding stations are always stocked with the necessary components to keep production lines moving efficiently.
