Smith LT104 Acetylene Brazing Tip for AT60 Tube

Reliable Brazing for HVAC Pros: Miller Smith LT104

When you are in the middle of an install or a critical repair, your torch needs to work as hard as you do. The Miller Smith LT104 Versa-Torch™ Screw-On Tip is the go-to choice for welders and HVAC technicians who rely on acetylene for their brazing work. Designed to tackle copper piping from 5/8 inch up to 1 inch, this tip hits the sweet spot for many refrigeration and plumbing lines. It delivers a hot, focused flame that gets your workpiece up to temperature fast, allowing you to flow silver solder or brazing rod smoothly for that perfect, leak-free seal.

One of the biggest frustrations on the job can be swapping out equipment. The LT104 solves this with its convenient screw-on design. If you are running a Versa-Torch setup with an AT60 or AT600 tube, this tip twists on in seconds. No hunting for a wrench or struggling with a stuck friction fit—just screw it on hand-tight and you are ready to light up. This modularity means you can carry a handful of different tips in your pocket and adapt to whatever pipe size the job throws at you without hauling multiple torch handles back and forth to the truck.

Quality matters when you are working with combustible gases. Miller Smith has a reputation for building gear that lasts, and the LT104 is no exception. Made in the USA, this tip is machined to strict tolerances. The #56 orifice isn't just a random hole; it's precision-drilled to ensure your flame doesn't sputter or wander. You get a clean, consistent cone that lets you control the heat exactly where you need it. Whether you are sweating a joint in a tight crawlspace or brazing on a rooftop unit, you can trust this tip to perform safely and consistently.

Don't let worn-out or clogged tips slow down your day. The LT104 is an affordable, high-performance upgrade for your acetylene kit. It’s built to handle the heat and designed to make your life easier. If you are working with standard HVAC copper sizes, keep a few of these in your toolbox. They are the reliable workhorse you need to get the job done right the first time, every time.
