Harris Model 23A90-5 Acetylene Welding Tip

Reliable Flame Control for Professional Welders

When you are under the hood or focusing on a delicate brazing joint, the quality of your flame dictates the quality of your work. The Harris Model 23A90-5 Welding and Brazing Tip is built to give you that perfect, soft cone you need for intricate metalwork. If you work with Acetylene or Hydrogen, this tip is designed to maximize the potential of your fuel gas. The construction uses tellurium copper, which isn't just durable—it handles heat incredibly well. This means the tip stays cleaner for longer and resists the deformation that can occur with inferior copper tips, keeping your flame straight and true job after job.

One of the biggest frustrations in gas welding is a sputtering or wandering flame caused by rough internal tip surfaces. Harris solves this with their swaging process. By polishing the inside of the tip to a mirror-like finish, the gas flows smoothly without turbulence. The result? A crisp, consistent flame that responds instantly to your regulator adjustments. You get the heat exactly where you want it, whether you are running a bead on thin sheet metal or heating a pipe fitting for silver brazing. The tip size 5 is a versatile middle-ground size, suitable for a wide array of material thicknesses commonly found in HVAC, automotive repair, and general shop maintenance.

Safety and setup speed are also key. The 23A90-5 features a metal-to-metal seat that locks into your mixer securely. You don't have to worry about rubber seals burning out or leaking gas near your hand. It tightens down for a positive seal every time. This tip fits Harris universal mixers (sizes 0-10), making it a flexible addition to your torch kit. If you already run Harris handles, this tip drops right in. It’s a workhorse component that helps you produce cleaner brazes and stronger welds with less hassle, letting you focus on your craftsmanship rather than fighting your equipment.
