0324-0188 - Victor Type 55-1 Size 6 Multi-Flame Heating Nozzle

Technical Overview of the Victor Type 55-1 Heating Nozzle

The Victor Professional Heating Nozzle, Type 55-1, Size 6 (SKU: 0324-0188), is a high-performance component engineered for heavy-duty industrial thermal applications. Designed specifically for use with alternative fuel gases—such as propane, natural gas, and propylene—this nozzle provides a high-capacity heat output suitable for demanding tasks like heat treating and metal straightening. It is explicitly not compatible with acetylene, ensuring that operators utilize the correct fuel source for high-volume heating requirements.

A defining technical feature of the Type 55-1 series is the raised center point located on the face of the head. This structural design element serves a critical function: it prevents the nozzle face from making flush contact with the work plate. By maintaining this separation, the design prevents the compression of the flame and protects the integrity of the nozzle head from physical deformation during aggressive use. Internally, the nozzle utilizes a unique mixer design that optimizes gas flow dynamics. This results in improved flow performance and significantly greater resistance to sustained backfire, a common hazard in high-output heating operations.

Operational requirements for the Size 6 nozzle are specific to ensure safety and performance. It must be paired with the Victor HD 310C torch handle. Furthermore, due to the high volume of gas flow required to sustain the multi-flame output, a 3/8-inch hose is mandatory. Smaller diameter hoses may restrict flow, leading to starvation of the flame or potential safety issues. This nozzle represents a robust solution for industrial fabrication shops requiring reliable, high-BTU output for large-scale metalworking.
