0040991301 - ESAB PKB 400 Replacement MIG Nozzle

Optimize Your MIG Torch with the ESAB 0040991301 Nozzle

The ESAB PKB 400 Gas Nozzle (Part No. 0040991301) is the definitive replacement choice for welders using the PKB 400 MIG gun system. Welding professionals know that the condition of the torch front-end is often the difference between a perfect bead and a rejected part. Over time, gas nozzles are subjected to extreme thermal cycling and spatter buildup, which can alter their geometry and obstruct gas flow. This genuine ESAB replacement restores your torch to factory specifications, ensuring that you get the smooth, stable arc and excellent coverage you expect.

Superior Heat Management and Durability
One of the primary challenges in MIG welding is heat management at the torch tip. This nozzle is fabricated from a robust copper alloy specifically selected for its thermal conductivity and durability. It effectively draws heat away from the contact tip and diffuser, helping to prevent burn-backs and extending the life of internal components. The heavy-duty construction also means it can withstand the accidental knocks and drops that are common in busy industrial environments without losing its shape.

Precision Gas Coverage
Shielding gas coverage is non-negotiable for quality welds. The ESAB 0040991301 nozzle features an optimized bore diameter and internal taper that focuses the gas column directly over the weld pool. This design minimizes turbulence and maximizes the efficiency of your shielding gas, whether you are using pure Argon, CO2, or a mixed gas blend. Proper gas coverage is essential for preventing porosity and ensuring that the mechanical properties of the weld meet code requirements.

Easy Maintenance and Installation
Designed for the practical needs of the welder, this nozzle is easy to install and remove for routine cleaning. Its resistance to spatter buildup means you spend less time scraping out the nozzle and more time welding. When spatter does accumulate, the high-quality surface finish allows for quick removal with standard nozzle pliers or anti-spatter dip. Keep your PKB 400 torch running at its best with this essential consumable, designed to deliver performance, longevity, and value in every arc start.
