19015 - ESAB R-5000 MIG Gun Nozzle 1/2 Inch Bore

Genuine ESAB 19015 R-5000 Gas Nozzle for Industrial MIG Systems

The ESAB 19015 Nozzle R-5000 is a premium-grade replacement consumable designed to maintain the high-performance standards of ESAB, Linde, and L-Tec MIG welding guns. Engineered specifically for the ST-16, ST-23, MT-200, and MT-400 series torches, this nozzle ensures precise fitment and reliable gas shielding in demanding industrial environments. With a 1/2-inch (12.7 mm) bore, it provides an optimal balance of gas coverage and accessibility, making it suitable for a wide range of medium-to-heavy duty fabrication tasks.

Manufactured from high-conductivity copper alloy, the R-5000 nozzle is built to withstand the intense thermal cycling inherent in continuous welding operations. The material's superior heat dissipation properties help prevent overheating, extending the service life of both the nozzle and the front-end consumables it protects. Its robust wall thickness resists deformation from accidental impacts and reduces the adherence of weld spatter, simplifying maintenance and cleaning intervals.

Proper gas shielding is critical for preventing weld defects such as porosity and oxidation. The ESAB 19015 features a smooth internal geometry that promotes laminar gas flow, ensuring the weld pool is effectively blanketed by the shielding gas. This attention to fluid dynamics results in cleaner welds with less post-weld cleanup required. Whether you are operating legacy equipment or maintaining a fleet of ESAB torches, utilizing genuine OEM parts like the 19015 nozzle guarantees that your equipment operates at the manufacturer's specified parameters.

This nozzle is an essential stock item for maintenance, repair, and operations (MRO) departments supporting structural steel, automotive, and general manufacturing sectors. Its reliability minimizes downtime associated with consumable failures, keeping production lines moving efficiently.
