0004450097 - ESAB GPB Propane Cutting Tip 200-250mm Heavy Duty

ESAB GPB Cutting Nozzle: Heavy-Duty Precision for Thick Plate

The ESAB GPB Cutting Nozzle (SKU: 0004450097) is a specialized oxy-fuel consumable engineered for the most demanding industrial cutting applications. Designed specifically for use with Propane and Natural Gas, this nozzle is rated for a cutting thickness range of 200mm to 250mm. This capability places it firmly in the heavy-duty category, making it an essential tool for shipyards, steel mills, scrap processing facilities, and heavy structural fabrication shops where standard cutting tips would be insufficient.

The GPB series utilizes a two-piece construction method, which is the industry standard for alternative fuel gases. The inner member is precision-machined from brass and features splines that define the preheat gas flow, while the outer sheath is crafted from high-quality copper to withstand intense heat and resist spatter adhesion. This design creates a stable, high-velocity preheat flame that compensates for the lower burning velocity of propane compared to acetylene. The result is a nozzle that can bring thick steel to ignition temperature efficiently and maintain a powerful cutting oxygen stream to penetrate up to 250mm of material.

Accuracy and durability are hallmarks of ESAB's manufacturing process. The 0004450097 nozzle features smooth internal gas passages that minimize turbulence, ensuring a laminar flow of oxygen. This is critical when cutting at such extreme thicknesses, as any diversion in the oxygen stream can cause the cut to wander or gouge the workpiece. The robust copper exterior also provides excellent thermal conductivity, helping to keep the nozzle cool even when reflected heat from the thick plate is substantial. Operators can expect longer service life and reduced downtime for tip changes.

When working with heavy plate, safety and efficiency are paramount. The ESAB GPB nozzle is designed to seat perfectly in compatible ESAB cutting torches, ensuring a leak-free seal and optimal gas mixing. Whether you are severing risers in a foundry or dismantling heavy machinery, this nozzle delivers the consistent performance required for professional results. It represents the intersection of ESAB's metallurgical expertise and practical engineering, providing a reliable solution for heavy-section thermal cutting.
