Execute balanced, 360-degree wraparound heating and uniform brazing on ring bands, tubing, and delicate micro-assemblies with genuine Miller® SMITH Twin Flame Tips. Purpose-built as precision replacement nozzles for the authentic Smith® Little Torch™, these curved dual-orifice copper tips envelope cylindrical workpieces with simultaneous opposing flames. Suitable for use across all standard fuel gases—including Acetylene, Hydrogen, Propane, Propylene, MAPP®, and Natural Gas paired with Oxygen—every tip is 100% factory flame-tested to ensure reliable, balanced gas flow and zero thermal cold spots on intricate joints.
Key Features & Benefits
-
360° Dual-Flame Wraparound Heating: Single-flame tips require constant hand rotation to heat cylindrical joints, increasing the risk of uneven solder flow and localized burning. The twin-arm architecture surrounds the workpiece, heating both sides simultaneously for smooth, void-free capillary brazing.
-
Universal Multi-Fuel Gas Compatibility: Engineered to operate efficiently with all common fuel gases (Acetylene, Hydrogen, Propane, Propylene, MAPP®, and Natural Gas) paired with Oxygen.
-
High-Thermal Output Range (4,300 to 9,500 BTU/hr): Available in three distinct orifice sizes (No. 4, No. 5, and No. 6) to support brazing capacities from 1/4” up to 7/8” copper tubing and heavy precious metal bands.
-
100% Factory Flame Tested: Precision-machined orifices are individually tested by Miller Smith to guarantee balanced gas flow, equal flame velocity on both arms, and reliable ignition straight out of the box.
