The Miller Smith 12-1401-07 is a size #7 curved tip designed specifically for the Smith Little Torch oxy-fuel system. Engineered for professional performance, this tip offers the highest standard heat output in the series, rated at 9,200 BTU/hr. It is an essential component for operators requiring a versatile flame capable of bridging the gap between micro-precision soldering and light-duty industrial brazing. The tip features a standard connection compatible with all Smith Little Torch handles (11-1101C and equivalent).
Technically, the 12-1401-07 is distinguished by its 0.047-inch (Drill Size 56) orifice. This bore size supports a fuel flow rate of 6.27 CFH and an oxygen flow rate of 7.52 CFH when set to the recommended pressure of 8 PSI. The tip utilizes a synthetic sapphire insert to define the flame cone, which provides superior resistance to heat erosion and ensures a laminar gas flow. This results in a "stiff," stable flame that does not flutter, even when the torch is moved rapidly. The tip is capable of producing flame temperatures up to 6,000°F, sufficient to melt commercially weldable metals, glass, and ceramics.
One of the primary benefits of the #7 tip is its multi-gas compatibility. It is rated for use with Acetylene, Hydrogen, Propane, Propylene, and Natural Gas. This makes it a go-to solution for shops running on alternative fuels. In practical application, the 12-1401-07 provides enough thermal transfer to braze copper pipes ranging from 1/2" to 7/8", making it suitable for HVAC and plumbing tasks in addition to its traditional roles in electronics repair and laboratory work.
