639755 - Oxweld FG-2 External Sleeve for Two-Piece Cutting Tips

Premium Performance with ESAB Oxweld FG-2 External Nozzles

The ESAB Oxweld FG-2 External Nozzle is a critical component for industrial cutting applications utilizing alternate fuel gases. Engineered to meet the rigorous demands of heavy fabrication and scrap cutting, this external sleeve is manufactured from hard-drawn, electrolytic, tough pitch copper. Unlike standard copper alloys, this pure copper construction provides superior thermal conductivity, ensuring maximum cooling during operation. This characteristic is essential when working with alternate fuels like propane or natural gas, which often require different preheat characteristics and can generate significant reflected heat during the piercing and cutting process.

As the external component of the renowned Oxweld two-piece nozzle system, the FG-2 is designed to work in perfect unison with the internal spline. The two-piece design is favored for alternate fuels because it allows for the optimization of the gas flow path, ensuring a stable and concentrated preheat flame. The FG-2 sleeve features a heavy-wall construction that resists deformation and wear, significantly outlasting comparable alloy nozzles. Its internal geometry is precision-machined to facilitate smooth gas flow, contributing to cleaner cuts with minimal kerf width.

One of the standout features of the Oxweld FG-2 is its serviceability. The nozzle is designed with long, parallel preheat passages. This engineering choice permits operators to re-dress the face of the nozzle using a file or abrasive stone to remove slag adherence or minor damage without altering the preheat flame characteristics or performance. This re-dressing capability, combined with the ability to replace the external sleeve independently of the internal section, makes the FG-2 a highly cost-effective solution for high-volume cutting environments.

At Josef Gas, we understand that precision and reliability are paramount in oxy-fuel cutting. The ESAB Oxweld FG-2 delivers on both fronts, providing a robust shield for your cutting stream and ensuring consistent performance shift after shift. Whether you are cutting structural steel or processing scrap, this external nozzle provides the durability required to maintain productivity.
