OVERVIEW

Extend the Life of Your TurboTorch Tips

Don't throw away your trusted TurboTorch tip just because the flame is acting up. The TurboTorch 0386-1031 STOR-3 Orifice is the perfect solution for bringing your ST-3 or ST-4 Extreme™ tip back to life. For professional plumbers, HVAC technicians, and maintenance pros, TurboTorch is the gold standard in air-acetylene brazing. However, even the best tools need maintenance. If you are experiencing a sputtering flame, difficulty lighting the torch, or a flame that just doesn't seem as hot as it used to be, the culprit is often a worn-out or clogged orifice.

This small but mighty part is the heart of your torch tip. It controls the flow of gas and ensures your torch mixes the perfect amount of air with the acetylene to create that signature wrap-around flame you depend on for quick copper pipe sweating and brazing. By replacing the orifice, you are essentially resetting the internal mechanics of the tip to factory-fresh condition. It is a smart, cost-effective alternative to buying a brand-new tip assembly, keeping more money in your pocket and less waste in the landfill.

Keep a spare STOR-3 orifice in your truck or toolbox so you are never caught off guard on a job site. When you're in the middle of a complex install or an emergency repair, the last thing you need is a tool failure. With this genuine TurboTorch replacement part, you can perform a quick field repair and get back to work in minutes. Designed specifically for the ST-3 and ST-4 models, it guarantees a perfect fit and safe operation every time.

Why Choose Genuine Parts?

Using generic or mismatched parts in gas torches can be dangerous and inefficient. The STOR-3 is precision-manufactured by TurboTorch to meet exact safety and performance standards. Ensure your welds and brazes are clean, consistent, and professional by maintaining your equipment with the right components.

FAQ

The STOR-3 orifice (0386-1031) is specifically designed for use with TurboTorch ST-3 and ST-4 Extreme™ Self Lighting Tips.

No, this orifice is designed for Air Acetylene applications used by the ST-3 and ST-4 tips. Propane tips typically require different orifice sizing and design.

Signs that your orifice may need replacing include a sputtering flame, a flame that is difficult to light, reduced heat output, or an irregular flame shape.

Yes, this is a genuine TurboTorch 0386-1031 replacement part, ensuring the same quality and safety as the original component.

No, the ST-5 and ST-6 tips require a larger orifice to handle the increased gas flow. You must use the specific orifice designed for those models.

This product typically includes the orifice itself. It is recommended to check your tip's filter screen during maintenance and replace it if it is clogged, though it is usually sold separately or in a kit.

Disassemble the tip from the handle, remove the old orifice (often using a wrench or specific tool depending on the tip model), and screw the new STOR-3 orifice securely into place. Ensure no debris enters the tip during the process.

The orifice creates the high-velocity gas stream required to pull in atmospheric air (venturi effect), creating the proper fuel-to-air mixture for a hot, stable flame.
