0311-0241 - Victor 8T55 Propane Heating Nozzle Size 8

Victor Professional 55 Series Multi-Flame Heating Head - Size 8

The Victor Professional 55 Series Multi-Flame Head (SKU: 0311-0241), also known as the 8T55, is a high-performance heating nozzle engineered for heavy industrial applications. Designed specifically for use with alternative fuel gases—such as Propane, Natural Gas, and Propylene—this heating head offers a safe and efficient solution for professionals requiring significant heat output without the use of Acetylene. The Size 8 configuration provides a substantial flame spread and BTU output, making it an essential component for large-scale fabrication and maintenance operations.

One of the defining technical characteristics of the 55 Series is its robust construction featuring a raised center point on the face of the head. This design element is critical for operational longevity; it prevents the nozzle face from making direct contact with the workpiece ("bumping the plate"), which can compress the flame and lead to overheating or damage. Furthermore, the internal geometry includes an improved mixer design that significantly enhances flow performance. This mixer is specifically tuned to handle the flow characteristics of alternative fuels, providing exceptional resistance to sustained backfire, a common hazard in heavy heating applications.

Compatibility is a key factor for the 0311-0241. It is designed to mate exclusively with the Victor HD 310C torch handle. Due to the high volume of gas required to sustain the multi-flame output, operators must utilize a 3/8-inch hose to ensure adequate flow rates are maintained. Using smaller hoses may starve the tip, leading to poor performance or safety issues. This nozzle is strictly for alternative fuels and must never be used with Acetylene due to the differences in gas pressure and combustion characteristics.

Industrially, this heating head is categorized under heavy-duty equipment. It is frequently employed in sectors such as structural steel fabrication, shipbuilding, and heavy equipment repair. The 8T55 excels in tasks requiring rapid heat transfer, such as pre-heating thick plates before welding, post-weld heat treating to relieve stress, and straightening bent steel members. Its ability to maintain a stable, high-intensity flame makes it a reliable choice for priming surfaces and descaling operations as well.
