Miller Smith 14711 Quickbraze Multi-Flame Acetylene Tip

Technical Specifications: Miller Smith 14711

The Miller Smith 14711 is a specialized multi-flame brazing tip designed for use with Acetylene fuel gas. It is a key component of the Smith Quickbraze line, engineered to provide high heat transfer rates for brazing copper tubing and pipe. The tip assembly features four distinct flame ports, creating a "rosebud" effect that broadens the heat zone compared to single-orifice welding tips. This configuration is critical for applications requiring the rapid heating of cylindrical workpieces, such as copper piping in refrigeration and HVAC systems.

Performance Characteristics

The 14711 is rated for a heat output of 13,760 BTU. The internal orifice diameter is .031 inches, corresponding to a #68 drill size. This specific flow rate and flame geometry allow the operator to effectively braze copper tubing with an Outer Diameter (O.D.) between 1/2 inch (12.7 mm) and 1-5/8 inches (41.2 mm). The multi-flame design ensures that the target temperature is reached quickly across the entire circumference of the joint, promoting capillary action for the brazing alloy.

Compatibility and Integration

This tip is designed with a quick-connect coupling for immediate attachment to Smith Quickbraze handles (specifically models 11-1114 and 11-1116). This connection style eliminates the need for wrenches during tip changes. Furthermore, the 14711 maintains backward compatibility with the Versa-Torch system; it can be threaded onto the AT40 Adaptor for use with standard Smith airline torch handles such as the AW1A and AW10A. Note that this tip is strictly for use with Acetylene and Oxygen; it is not compatible with alternate fuel gases like Propane or Propylene due to the specific flame propagation characteristics required by the orifice design.

Manufactured in the USA, the 14711 adheres to Miller Smith's rigorous quality control standards for gas equipment. It is an ideal solution for technicians requiring a dedicated acetylene brazing tip for medium-diameter piping applications.
