21328 - ESAB PT-20/21AMX 100A Plasma Cutting Nozzle (5-Pack)

High-Performance 100 Amp Plasma Nozzle for PT-20/21AMX Systems

The ESAB 21328 Nozzle is a critical consumable component engineered for the PT-20 and PT-21AMX plasma cutting torches. Designed to operate at 100 Amps, this nozzle is responsible for constricting the plasma arc to a high-density stream, enabling the precise and rapid severing of conductive metals. As a genuine ESAB product, it is manufactured to exact tolerances, ensuring that the orifice remains perfectly centered and shaped to maintain cut angularity and minimize dross accumulation.

In high-amperage plasma cutting, the nozzle is subjected to extreme thermal stress and erosion from the plasma gas. The ESAB 21328 is constructed from high-quality copper alloys that provide excellent thermal conductivity, helping to dissipate heat effectively and prolong the service life of the part. Using genuine OEM nozzles is essential for maintaining the validity of your equipment's performance specifications. Inferior aftermarket copies often suffer from poor machining, which can lead to double-arcing, reduced consumable life, and potential damage to the torch head itself.

This product is supplied as a package of five (5) nozzles, offering a practical solution for industrial environments where continuous operation is required. Regular inspection and replacement of the nozzle are standard maintenance procedures; a worn or oval-shaped orifice will degrade cut quality significantly. By keeping a stock of these 100 Amp nozzles, operators can ensure their PT-20 or PT-21AMX systems are always ready to deliver professional-grade results. These components are proudly made in the United States, adhering to ESAB's strict quality assurance protocols.

Whether utilized in automated cutting tables or manual fabrication setups, the ESAB 21328 nozzle provides the stability and consistency needed for heavy-duty applications. It integrates seamlessly with the torch's gas distribution system to shape the arc for deep penetration and smooth edge finishes on mild steel, stainless steel, and aluminum.
