0302-0042 - Victor 0302-0042 Type MFA Heating Nozzle, Size 12

Technical Overview of the Victor MFA Heating Nozzle

The Victor 0302-0042 is a Type MFA heating nozzle, specifically Size 12, engineered for heavy-duty industrial heating applications. This multi-flame head is designed to operate exclusively with Acetylene gas, providing a concentrated and high-intensity heat source required for demanding metalworking tasks. The nozzle is compatible with Victor 300 Series torch handles, such as the 315FC, making it a standard component for professionals utilizing heavy-duty oxy-acetylene equipment.

Constructed from high-grade copper and brass, the MFA Size 12 nozzle ensures superior thermal conductivity and longevity under high-heat conditions. The assembly features Victor's signature double O-ring seal design, which provides a secure, leak-proof fit within the torch handle, minimizing maintenance downtime and enhancing operational safety. The multi-flame configuration distributes heat evenly across the target area, which is critical for processes that require uniform temperature elevation without localized melting or distortion.

This nozzle is categorized under Victor's heavy-duty line, distinguishing it from the smaller MFA-1 series used with 100 Series handles. The Size 12 orifice arrangement allows for significant gas flow, generating the BTU output necessary for heating large cross-sections of steel. It is an essential component for MRO (Maintenance, Repair, and Operations) environments where structural straightening, large-scale bending, and preheating of castings or weldments are routine procedures.
