0311-0664 - Victor 20-MFN Propane/Natural Gas Heating Nozzle

Heavy-Duty Heating with Victor Reliability

The Victor 20-A-MFN Heating Tip (0311-0664) is a premier choice for industrial professionals requiring substantial heat output using alternative fuels. Designed specifically for Propane and Natural Gas, this multi-flame nozzle—often referred to as a "rosebud"—is engineered to deliver a high volume of heat efficiently and safely. It is an essential component for heavy fabrication shops, shipyards, and structural steel environments where preheating large assemblies is a daily requirement.

This Size 20 tip represents one of the larger capacities in the MFN series, capable of generating significant BTUs to quickly bring thick metal sections up to working temperature. Whether you are performing preheating prior to welding, straightening bent steel members, or bending pipe and plate, the 20-A-MFN provides the consistent, wide-area flame needed to soak heat deep into the base material without the localized overheating often associated with smaller tips.

Built to Victor's exacting standards, the nozzle features durable brass and copper construction that withstands the rigors of harsh industrial environments. Its internal geometry is optimized to maintain a stable flame even at high flow rates, ensuring reliable performance during extended heating cycles. By utilizing Propane or Natural Gas, operators can also benefit from the cost savings associated with these fuels compared to Acetylene, without sacrificing the total heat energy required for massive jobs.

Key Applications

• Preheating: Preparing thick steel plates and castings for welding to prevent cracking.


• Straightening: Applying heat to correct warping in structural beams and frames.


• Bending: Heating pipe or bar stock to facilitate forming.


• Descaling: Flame cleaning surfaces in heavy maintenance operations.
