0311-0306 - Victor Size 3 MFN Propane Heating Nozzle

Victor 0311-0306 3-TEMFN Heating Tip Overview

The Victor 0311-0306 3-TEMFN Heating Tip is a premium-grade multi-flame nozzle engineered for industrial heating applications requiring the use of alternative fuels such as Propane and Natural Gas. As part of the renowned Victor gas equipment line, this heating tip—commonly referred to as a "rosebud"—is designed to deliver high-volume heat output efficiently and safely. The "MFN" designation specifically indicates its optimization for natural gas and propane, distinguishing it from MFA tips used with acetylene. This distinction is critical for safety and performance, as the combustion characteristics of alternative fuels require specific internal geometries to maintain a stable flame and prevent issues like flashback or flame lift-off.

With a Size 3 rating, this tip offers a versatile heat range suitable for a wide variety of maintenance, repair, and fabrication tasks. It is constructed from high-quality copper alloy, ensuring excellent thermal conductivity and resistance to the harsh environments typical of heavy industrial work. The multi-flame design distributes heat over a larger surface area compared to single-point cutting tips, making it the ideal tool for preheating weldments, straightening bent steel structures, bending pipes, and descaling metal surfaces. The robust construction ensures a long service life, even under continuous high-heat conditions found in shipyards, structural steel shops, and heavy equipment repair facilities.

Integrating the Victor 3-TEMFN into your oxy-fuel setup allows for significant operational cost savings by leveraging cheaper fuel gases for heating processes that consume large volumes of gas. The tip attaches securely to compatible Victor heavy-duty torch handles and cutting attachments, providing a leak-proof seal and reliable gas flow. Whether you are bringing a thick plate up to interpass temperature or freeing a seized heavy equipment pin, the 0311-0306 provides the consistent, soaking heat required to get the job done efficiently.

Key Industrial Applications

• Structural Steel Fabrication: Essential for preheating thick columns and beams prior to welding to prevent cracking.


• Heavy Equipment Repair: Used for heating seized bearings, pins, and nuts to facilitate removal.


• Pipe Bending: Provides the broad, even heat necessary to bend large diameter pipes without kinking.


• Metal Straightening: Applies localized heat to correct distortions in steel plates and frames (flame straightening).
