LT106 - Miller Smith LT106 Versa-Torch Acetylene Brazing Tip, Size 52

Technical Specifications of the Miller Smith LT106 Versa-Torch Tip

The Miller Smith LT106 is a precision-engineered brazing tip designed for use within the Versa-Torch ecosystem, specifically tailored for oxy-acetylene applications. This component is critical for professionals requiring exact thermal output for joining copper piping and similar materials. The tip features a specific orifice geometry, designated as Drill Size 52, which calibrates the gas flow rate and velocity to produce a soft, concentrated flame ideal for capillary brazing operations. The internal fluid dynamics of the tip are optimized to prevent flame lift-off and flashback, ensuring operational safety and consistency during prolonged use.

Mechanically, the LT106 utilizes a threaded screw-on connection interface. This design choice eliminates the need for friction-fit or swaged connections, providing a positive seal that resists leaks even under thermal expansion and contraction cycles. It is explicitly engineered to mate with Miller Smith AT60 and AT600 threaded tip tubes, forming a rigid and reliable assembly. The thermal mass of the tip is balanced to maintain preheat temperatures without overheating the torch assembly, a crucial factor when working in confined spaces typical of HVAC installations.

In terms of capacity, the LT106 is rated for brazing copper pipe diameters ranging from 3/4 inch to 1-1/2 inches (19 mm to 38 mm). This range covers a significant portion of residential and light commercial refrigerant linesets, making it a staple consumable for the trade. The tip construction involves high-quality brass and copper alloys, selected for their thermal conductivity and resistance to oxidation at high temperatures. Proper maintenance involves regular inspection of the seating surface and cleaning of the orifice with appropriate tip cleaners to maintain the Drill Size 52 specification and ensure optimal flame characteristics.

The Versa-Torch system's modularity allows the LT106 to be part of a flexible toolkit where operators can rapidly switch between heating, welding, and brazing tips without changing the entire torch handle. This efficiency is paramount in industrial MRO environments where time and precision are equivalent to cost savings. The LT106 represents the intersection of durability, precision manufacturing, and practical field application design.
