66Z63 - Oxweld 1502 Series Acetylene Cutting Tip - Size 12

Precision Cutting with ESAB Oxweld 1502 Series

The ESAB Oxweld 66Z63 is a premium Size 12 cutting tip from the renowned 1502 Series, engineered specifically for acetylene gas applications. For decades, the Oxweld brand has been synonymous with industrial-grade reliability and performance in oxy-fuel cutting. This nozzle exemplifies that legacy, offering a robust solution for fabrication shops, scrap yards, and heavy industrial maintenance where cutting thick steel sections is a daily requirement.

Constructed from a single piece of hard copper, the 66Z63 is designed to withstand intense heat and harsh working environments. Unlike multi-piece tips that can separate or leak under thermal stress, this solid construction ensures maximum thermal conductivity, keeping the tip cooler during extended operation. This design significantly extends the service life of the consumable, reducing downtime and replacement costs for high-volume operations.

The internal geometry of the 1502 series is swaged, a manufacturing process that creates a mirror-smooth internal passage for the cutting oxygen. This laminar flow minimizes turbulence as the oxygen stream exits the tip, resulting in a tighter, more coherent cutting stream. For the operator, this translates to faster cutting speeds, cleaner kerfs, and less slag adhesion on the finished edge. The Size 12 specification provides a substantial cutting capacity, capable of slicing through steel plates up to 4 inches thick with precision and ease.

Compatibility is key in industrial settings, and the 66Z63 fits seamlessly with all standard Oxweld cutting torches, including the C-32, C-66, C-77, and C-97 models. The tip features Oxweld's signature metal-to-metal seating surface, which eliminates the need for rubber O-rings that can dry out or crack. This ensures a positive, leak-proof seal every time the tip is tightened into the torch head. Whether you are performing structural demolition or precision fabrication, the ESAB Oxweld 1502 Series Size 12 tip delivers the consistent preheat and powerful cutting stream necessary for professional results.
