0338-0022 - Victor MFN Series Replacement Tip Shell (Sizes 10-15)

Technical Overview of Victor 0338-0022

The Victor 0338-0022 is a specialized replacement tip shell engineered for the MFN series of multi-flame heating nozzles. Manufactured by Victor Technologies (ESAB), this component is critical for the proper assembly and function of heavy-duty heating attachments used in industrial oxy-fuel applications. The shell is designed to house the internal mixer or insert of the heating nozzle, directing the flow of pre-mixed fuel gas and oxygen to the flame face. Specifically calibrated for use with alternate fuels such as Propane and Natural Gas, this shell is not compatible with Acetylene (MFA) nozzles due to differences in flow characteristics and recess requirements.

Compatibility and Specifications

This specific part number, 0338-0022, is the designated outer shell for MFN heating nozzles in sizes 10, 12, and 15. These larger nozzle sizes are typically employed in high-output heating operations requiring significant BTU transfer, such as preheating thick plate or bending large structural members. The shell features precision-machined threads that mate securely with the torch head or mixer assembly, ensuring a gas-tight seal to prevent backfires or leakage. Constructed from a high-grade copper alloy, the shell provides excellent thermal conductivity and resistance to oxidation at elevated temperatures.

Maintenance and Replacement

In the MFN assembly, the outer shell is subject to intense radiant heat and physical wear from the work environment. Over time, the seating surfaces may degrade, or the tip end may become damaged from spatter or accidental impact. Replacing the shell with the genuine Victor 0338-0022 restores the nozzle's structural integrity and flame shaping capabilities. It is essential to verify the nozzle series (MFN) and size range (10-15) before installation to ensure safe operation. This component is sold individually and does not include the internal mixer insert.
