Oxweld 4203 Propane Cutting Tip - Size 5

ESAB Oxweld 16K16 - 4203 Series Propane/Natural Gas Nozzle

Maximize the performance of your oxy-fuel cutting setup with the ESAB Oxweld 16K16 Cutting Tip. Part of the renowned 4203 Series, this Size 5 nozzle is specifically engineered for welders and fabricators utilizing Propane or Natural Gas. While acetylene has long been the standard, many modern shops prefer alternative fuels for their economy and safety; the 4203 series is the perfect companion for these gases, featuring a specialized two-piece design that optimizes flame characteristics for slower-burning fuels.

The internal geometry of the 16K16 is designed to produce a heavy preheat flame, which is essential for piercing and maintaining the cut on thick sections of steel. The Size 5 rating indicates a robust cutting capacity, suitable for material thicknesses in the range of 6 inches. This makes it a versatile tool for heavy fabrication, demolition, and infrastructure work. The tip fits all standard Oxweld-style torches, including the popular C-32 and C-66 models, offering a seamless upgrade or replacement for worn-out consumables.

Constructed from high-quality copper alloy, the tip is built to withstand intense reflected heat. The chrome plating acts as a shield against oxidation and spatter buildup, making cleaning easier and prolonging the life of the nozzle. The separation of the inner and outer parts allows for easy maintenance and inspection. When paired with the correct pressure settings, this tip delivers a high-velocity oxygen stream that clears molten metal rapidly, resulting in high-quality cuts with excellent edge definition.

Trust in the legacy of Oxweld quality. The 16K16 nozzle provides the consistency and reliability professional welders demand. Ensure your torch is equipped to handle heavy plate with precision by choosing genuine ESAB consumables.
