LT104 - Smith LT104 Acetylene Brazing Tip for AT60 Tube

Precision Acetylene Brazing with the Miller Smith LT104

The Miller Smith LT104 Versa-Torch™ Screw-On Tip is a specialized component designed for professional brazing and heating applications utilizing acetylene gas. Engineered to meet the rigorous demands of the HVAC and plumbing industries, this tip represents the high standards of manufacturing associated with the Miller and Smith Equipment brands. The LT104 is specifically calibrated with a drill size of 56, which optimizes gas flow to produce a concentrated and controllable flame. This precision is critical for operators who require consistent thermal output to ensure sound metallurgical bonds during the brazing process.

Compatibility is a key feature of the LT104. It is designed to interface seamlessly with the AT60 and AT600 threaded tip tubes, utilizing a secure screw-on mechanism. This design choice eliminates the need for cumbersome tools during tip changes, allowing technicians to switch between different tip sizes rapidly as job site requirements evolve. The threaded connection ensures a gas-tight seal, preventing leaks and maintaining safety standards during operation. By integrating with the broader Versa-Torch™ system, the LT104 enhances the utility of existing torch setups, making it a cost-effective addition to any professional's toolkit.

In terms of capacity, the LT104 is rated for brazing copper pipe with diameters ranging from 5/8 inch to 1 inch (16 mm to 25 mm). This range covers a significant portion of standard residential and light commercial piping used in air conditioning and refrigeration systems. The tip delivers the necessary BTU output to bring these pipe sizes to brazing temperature efficiently without overheating the base metal or damaging sensitive surrounding components. The ability to maintain a stable flame profile helps in drawing the filler metal deep into the capillary space, ensuring leak-proof joints that stand the test of time.

Manufactured in the United States, the Miller Smith LT104 is built from durable alloys capable of withstanding high operating temperatures and the physical rigors of field work. The tip's geometry is optimized to resist backfire and maintain a clean flame cone, even under varying pressure conditions. For industrial MRO analysts and procurement specialists, the LT104 represents a reliable, specification-compliant solution for maintenance teams requiring dependable oxy-acetylene tooling.
