0387-0065 - Victor 15-MFA Acetylene Heating Nozzle Size 15

Victor 15-MFA-CS Heating Nozzle: Industrial Grade Acetylene Heating

The Victor 15-MFA-CS (SKU: 0387-0065) is a premium heating nozzle designed for heavy-duty industrial applications requiring significant heat input. Part of the renowned MFA series, this nozzle is engineered specifically for use with Acetylene gas, leveraging the high flame temperature and heat transfer properties of oxy-acetylene combustion. The "MFA" designation stands for Multi-Flame Acetylene, indicating its configuration as a "rosebud" style tip that produces a broad, intense heat pattern suitable for large-scale thermal operations.

This specific model is a Size 15, which places it at the higher end of the capacity spectrum for manual heating torches. It is designed to fit Victor 300 Series torch handles (such as the HD 310C), which are necessary to supply the substantial volume of oxygen and fuel gas required for a tip of this magnitude. The nozzle features a one-piece construction, ensuring structural integrity and minimizing leak paths under the thermal stress of operation. The precision-drilled orifices are arranged to provide a stable, coherent flame that resists popping and backfire when used within recommended pressure parameters.

The "CS" in the part number indicates that this product comes in Clamshell packaging, suitable for retail display and providing protection for the seating surfaces during transit. Industrial professionals rely on the 15-MFA for tasks such as preheating heavy plate prior to welding, straightening bent structural members, bending pipe or bar stock, and shrinking fitted parts. Its ability to deliver a large volume of heat quickly makes it an essential tool for fabrication shops, shipyards, and heavy equipment repair facilities where time and thermal efficiency are critical.

Proper gas supply is crucial when using the 15-MFA. Due to the high withdrawal rate of acetylene required by a size 15 tip, operators must ensure their cylinder manifold system can sustain the necessary flow without exceeding the 1/7th (or 1/10th) withdrawal rule to prevent solvent withdrawal from the acetylene cylinder. This nozzle represents the standard of excellence in oxy-acetylene heating, combining Victor's legacy of quality with robust performance characteristics.
