16K14 - Oxweld 4202 Size 12 Propane/Natural Gas Cutting Tip

Heavy-Duty Industrial Cutting Performance

The ESAB Oxweld 4202 Series Cutting Tip (Size 12), identified by part number 16K14, is a premium consumable designed for heavy industrial fabrication and scrapping operations. Engineered specifically for alternate fuel gases—namely Natural Gas and Propane—this nozzle leverages the unique combustion properties of these gases to deliver deep, penetrating heat and a powerful oxygen stream capable of severing carbon steel up to 12 inches (300mm) thick.

The 4202 series features a robust two-piece construction. The internal brass spline fits precisely within a heavy-wall copper outer shell. This design is critical for alternate fuels, as it creates a recess at the tip end that anchors the flame, preventing blow-offs even at the high flow rates required for cutting thick sections. The copper shell provides superior heat dissipation, extending the lifespan of the tip even when exposed to the intense radiant heat generated during heavy plate cutting. The internal geometry is optimized to maintain a laminar oxygen flow, ensuring straight, clean cuts with minimal kerf width and slag accumulation.

This Size 12 nozzle is an essential component for facilities utilizing bulk propane or natural gas lines, offering significant cost savings over acetylene for heavy sectioning tasks. It is fully compatible with standard Oxweld torches, including the C-32, C-66, and machine torches, making it a versatile addition to any heavy-duty oxy-fuel setup.
