2218723 - ESAB 2218723 Replacement Oxygen and Fuel Gas Tube

Technical Overview of the ESAB 2218723 Gas Tube

The ESAB 2218723 Oxygen & Fuel Gas Tube is a specialized replacement component engineered for the maintenance and repair of industrial oxy-fuel cutting attachments. As a genuine Original Equipment Manufacturer (OEM) part, it is manufactured to the precise dimensional tolerances and material specifications required by ESAB, Oxweld, and Purox equipment lines. This component plays a critical role in the internal gas distribution system of the torch, serving as the dedicated conduit that transports oxygen and fuel gas from the handle or valve body to the mixing chamber or head assembly.

In oxy-fuel cutting processes, the integrity of internal tubing is paramount for both safety and performance. Over time, internal tubes can suffer from fatigue due to thermal cycling, mechanical stress, or accidental damage during field use. A compromised tube can lead to internal gas mixing or external leaks, presenting significant safety hazards such as flashbacks or torch fires. The 2218723 tube is constructed from high-quality metallic alloys, typically brass or copper-based, designed to resist corrosion and withstand the pressures associated with industrial cutting gases. Its form factor is pre-bent and shaped to fit specific torch geometries, ensuring a tension-free installation that does not stress the connection points.

Maintenance personnel and tool crib managers should utilize this part when refurbishing cutting attachments that exhibit flow irregularities or physical damage to the gas transport lines. Installing genuine ESAB parts ensures that the flow characteristics—turbulence, pressure drop, and volume—remain within the design parameters of the torch, thereby preserving the quality of the cut and the stability of the preheat flame. This part is supplied as a single unit, ready for installation by qualified equipment repair technicians.
