Victor 0323-0250 Heating Nozzle for Acetylene
This Victor 0323-0250 heating nozzle fits 300 series and HD 310C torches using MFA tip series. It delivers a multi-flame pattern for heat treating, priming and straightening tasks. The size 4 tube-and-head design handles acetylene fuel at a minimum pressure of 6 psig. Oxygen flow ranges from 7 to 22 scfh for controlled heating.
Practical Flow Limits and Torch Compatibility
Oxygen flow must stay between 7 and 22 scfh to match the nozzle design. Acetylene supply requires at least 6 psig at the torch inlet. The nozzle only fits Victor 300 series, HD 310C and 315FC torch handles listed in the specifications. Using other torch models or exceeding the flow range can damage the tip or produce an unstable flame.
Replaces Worn MFA Size 4 Tips on Compatible Torches
This nozzle replaces a worn or damaged MFA size 4 tip on the same torch series. The jump is worth it when the old tip shows pitting, flame distortion or inconsistent heat output. It restores the original multi-flame pattern for the same heating applications. Buyers needing a different tip size, fuel type or torch connection will need a different nozzle.

Questions about this item
Which tip size should I pick for my acetylene torch?
The 4-MFA nozzle is a single tip size 4 rated for acetylene; select it when your torch series and application match the listed compatibilities.
What does the 22 scfh oxygen flow mean in use?
It is the maximum oxygen flow the nozzle can deliver; actual flow will depend on your regulator setting and torch model.
How does the 6 psig fuel pressure rating limit the setup?
The nozzle requires at least 6 psig acetylene pressure; operating below that will prevent proper multi-flame performance.
