Victor Size 15 Acetylene Heating Nozzle
This Victor heating nozzle is a Size 15 acetylene tip designed for the HD 310C torch series and MFA tip series. It suits technicians performing heat treating, priming and straightening tasks where a multi-flame tube and head design is required. The nozzle is compatible with Grainger part numbers 25DV27, 25DV28 and 5KJ44.
Installation and common issues
The nozzle threads onto the compatible HD 310C torch using the MFA tip connection, so fitting is straightforward when the torch series matches. Problems usually arise if the acetylene regulator cannot supply at least 12 psig or if oxygen flow falls below 99 scfh or exceeds 244 scfh, causing unstable flames or tip overheating.
Practical limits of the acetylene interface
The acetylene fuel interface demands a minimum fuel pressure of 12 psig and oxygen flow between 99 and 244 scfh for stable multi-flame operation. Performance drops off outside this window, and the nozzle cannot be used with propane or other fuel types. Buyers needing higher heat output or different flame patterns should select a larger tip size or alternative tip series.

Questions about this item
How do I confirm the nozzle is delivering the correct multi-flame pattern after connecting it to my HD 310C torch?
Light the torch and verify a stable multi-flame envelope; the oxygen flow should fall between 99 and 244 scfh while acetylene pressure stays at or above 12 psig.
What comes in the package and which fittings or hoses must I supply separately?
The box contains one size 15 acetylene heating nozzle (tip series MFA, tube-and-head design); torch handle, hoses, regulators and oxygen/acetylene supply are not included.
When should I choose this size 15 tip instead of a smaller or larger MFA tip for heat treating or straightening?
Select the size 15 tip when your application requires the 99–244 scfh oxygen range and 12 psig minimum acetylene pressure; smaller tips use lower flows, larger tips need higher flows.
