598739 - ESAB PSF Series MIG Gas Nozzle 16mm (Pack of 2)

Precision Gas Shielding for ESAB PSF Torches

The ESAB 16/21 Gas Nozzle is a critical consumable designed to maintain the performance and reliability of your ESAB PSF series MIG guns. Engineered with a standard 16mm bore, this nozzle provides the ideal balance of gas coverage and accessibility for a wide range of welding applications. The "16/21" designation refers to the 16mm inner diameter and 21mm outer diameter, a standard configuration for heavy-duty torches like the PSF 405 and PSF 505. Proper shielding gas flow is essential for preventing porosity and atmospheric contamination in the weld pool, and this nozzle is manufactured to exacting tolerances to ensure laminar flow and consistent protection.

Constructed from high-quality copper alloy, the nozzle is built to withstand the intense heat and spatter associated with industrial MIG welding. The material offers excellent thermal conductivity, helping to pull heat away from the contact tip and diffuser, thereby extending the lifespan of your front-end consumables. Its robust design resists deformation under thermal stress, ensuring a secure fit on the torch neck throughout its service life. This pack contains two nozzles, providing a necessary backup for high-volume production environments where uptime is paramount.

Compatibility is key with MIG consumables, and this nozzle is specifically tailored for the ESAB PSF line. Using genuine ESAB parts ensures that the electrical isolation and gas sealing properties of the torch are maintained, preventing arc wandering or gas leakage. Whether you are welding structural steel, heavy machinery, or general fabrication projects, the 16mm orifice offers versatile performance for spray transfer and short-circuit modes alike.
