16K16 - Oxweld 4203 Propane Cutting Tip - Size 5

Heavy-Duty Oxweld 4203 Series Cutting Tip for Alternative Fuels

The Oxweld 4203 Size 5 Cutting Tip (SKU: 16K16) is a premium consumable manufactured by ESAB, designed specifically for industrial cutting applications using Propane or Natural Gas. Unlike standard acetylene tips, the 4203 series utilizes a two-piece construction consisting of a heavy-duty copper outer shell and a splined brass inner member. This design is critical for alternative fuels, as it creates a stable, high-velocity preheat flame necessary to bring the base metal to ignition temperature quickly and efficiently.

With a Size 5 orifice, this nozzle is engineered for substantial cutting tasks, capable of slicing through steel plates up to approximately 6 inches in thickness. It is an ideal choice for scrap yards, structural steel fabrication, and heavy equipment repair where propane or natural gas is the preferred fuel gas due to cost-effectiveness or availability. The tip features precision-machined seating surfaces that ensure a secure, gas-tight fit into standard Oxweld cutting torches, preventing dangerous leaks and ensuring consistent performance.

Durability is a hallmark of the Oxweld brand. The outer sleeve is chrome-plated to resist corrosion and minimize the adherence of spatter, extending the service life of the tip even in harsh working environments. Whether you are performing manual hand cutting or using a machine torch, the 16K16 nozzle delivers a coherent oxygen stream that produces smooth, square cuts with minimal slag accumulation, reducing the need for secondary grinding.

At Josef Gas, we understand the importance of reliable consumables. This genuine ESAB/Oxweld part ensures that your cutting equipment operates at peak efficiency, providing the heat and control needed for professional-grade results.
