0386-1001 - TurboTorch OR-A3 Replacement Orifice for A-3 and T-4 Tips

Precision Gas Control for Professional Brazing

The TurboTorch OR-A3 Replaceable Orifice (SKU: 0386-1001) is a critical maintenance component designed to restore the functionality of specific TurboTorch air acetylene tips. Engineered with the high tolerances expected from the leader in swirl combustion technology, this orifice is the exact OEM part required for the A-3 and T-4 tip models. Over time, the intense heat and carbon buildup associated with brazing and soldering can degrade the internal geometry of a torch tip's orifice. This wear leads to irregular gas flow, sputtering flames, and reduced heat output, which can compromise the quality of a joint. By replacing the orifice, users can return their equipment to factory-specification performance without the expense of purchasing a completely new tip assembly.

The OR-A3 is manufactured from high-quality brass, ensuring resistance to the thermal expansion and contraction cycles inherent in torch operations. Its internal bore is precision-drilled to meter the air-acetylene mixture accurately, a requirement for generating the high-velocity vortex flame that TurboTorch is famous for. This specific flow rate is calibrated for the A-3 and T-4 tip sizes, which are commonly used for medium-duty plumbing and HVAC applications. Installing the wrong orifice can lead to dangerous backfires or insufficient heat; therefore, utilizing the genuine OR-A3 ensures safety and efficiency. The component threads easily into the base of the tip, making it a field-serviceable part that minimizes downtime.

Professional tradespeople understand that the efficiency of a torch is dictated by the precision of its components. A worn orifice doesn't just affect the flame shape; it affects gas consumption. A distorted orifice can cause excessive gas use without delivering the concentrated heat needed to wrap around copper tubing. The OR-A3 rectifies this, ensuring that every tank of acetylene is used effectively. Whether performing silver brazing on refrigeration lines or soft soldering on water pipes, the integrity of the orifice is paramount. This replacement part is an essential addition to any service kit, ensuring that a clogged or damaged tip doesn't halt progress on the job site.
