Victor 0325-0105 Heating Nozzle

The Victor 0325-0105 is a MFA-J Series heating nozzle built for acetylene fuel and J-series torches such as the J-28 and J-40. It suits technicians performing heat treating, priming and straightening tasks.

Tube & Head Tip Design

The tube and head tip design produces a multi-flame pattern that distributes heat evenly across the workpiece. This geometry supports consistent results during priming and straightening operations without needing additional attachments.

Flow Range and Pressure Limits

Oxygen flow operates between 7 and 22 scfh at a minimum pressure of 6 psig, while acetylene requires at least 6 psig fuel pressure. The size 4 tip covers medium-duty heating jobs; larger or smaller tips are needed for higher or lower heat output.

Questions about this item

How often does the size-4 MFA-J tip need replacement under normal heat-treating use?

The tip is a wear part; lifespan depends on flame intensity and material thickness, so inspect the multi-flame orifices regularly and replace when the pattern degrades.

What is the first limit reached when running the nozzle continuously at high heat?

The 22 scfh maximum oxygen flow rate caps sustained output; exceeding it starves the flame and overheats the tube-and-head assembly.

How hot does the nozzle body get during all-day straightening work?

The tube-and-head design radiates significant heat; expect the body to become too hot to touch, so use heat-resistant gloves and allow cool-down periods.
