0390-0095 - Victor ST400 Series Replacement Torch Tubes

Technical Overview of Victor 0390-0095 Replacement Tubes

The Victor 0390-0095 represents a critical repair component for the ST400 series of straight cutting torches. These torches, widely recognized in the industrial sector for their durability and performance, rely on a specific triangular tube design to maintain structural rigidity and separate gas flow paths. This product consists of the replacement tube assembly necessary to refurbish a torch body that has suffered mechanical damage, such as bending or crushing, which is a common occurrence in heavy-duty fabrication environments.

Manufactured from high-grade stainless steel, these tubes are designed to withstand the internal pressures of oxygen and fuel gases while resisting external physical abuse. The integrity of these tubes is paramount; a compromised tube can lead to gas mixing within the handle or leaks that pose significant safety hazards. By utilizing genuine Victor OEM parts, maintenance personnel ensure that the replacement tubes match the exact dimensional specifications and threading of the original torch head and handle assembly. This precise fitment is essential for maintaining the gas-tight seals required for safe oxy-fuel cutting operations.

The ST400 series torches are engineered with a "tube-in-tube" or multi-tube design that separates the cutting oxygen from the preheat gases. The 0390-0095 kit restores this functionality, ensuring that the laminar flow of gases remains turbulent-free until the mixing chamber. This is critical for maintaining the flame characteristics that Victor torches are known for. When installing these components, it is recommended to inspect all O-rings and seating surfaces to prevent leaks. This repair part allows facilities to extend the service life of their capital equipment significantly, providing a cost-effective alternative to purchasing new torch assemblies.

In summary, the 0390-0095 is not merely a spare part but a restoration component that brings a compromised ST400 torch back to factory safety and performance standards. It is compatible with various models within the ST400 family, including the ST400C, and is suitable for use with all standard fuel gases supported by the torch design.
