OVERVIEW

Professional Grade Soldering and Brazing Performance

The TurboTorch STK-31 Dual Fuel Hand Torch (0386-0575) represents the gold standard for HVAC technicians and professional plumbers who demand reliability and speed. Engineered with TurboTorch's proprietary Extreme Swirl technology, this torch delivers a high-heat, wrap-around flame that ensures even heat distribution on copper pipes. Whether you are soldering small diameter tubing or brazing larger lines, the STK-31 provides the thermal efficiency needed to complete jobs quickly and effectively.

Versatility and Ease of Use

One of the standout features of the STK-31 is its 360-degree swivel tip. In the tight confines of a crawl space, under a sink, or inside an HVAC unit, the ability to rotate the tip allows you to direct the flame exactly where it is needed without contorting your hand or the cylinder. The torch is designed to operate on both Propane and MAP-Pro (propylene) gases, giving you the flexibility to choose the fuel that best suits your specific application and budget. The CGA-600 connection ensures compatibility with standard disposable cylinders found at most supply houses.

Durability and Maintenance

Built to withstand the rigors of daily field use, the STK-31 features a rugged brass regulator and tip assembly. Maintenance is simplified with easy-to-clean orifice screws, allowing users to quickly clear obstructions and maintain optimal flame performance. Unlike complex self-lighting torches that can fail over time, this manual ignition system is straightforward and reliable, requiring only a standard striker. For professionals seeking a benchmark tool that combines power, flexibility, and durability, the TurboTorch STK-31 is the essential choice for your toolbox.

FAQ

The STK-31 is a dual fuel torch, meaning it is compatible with both Propane and MAP-Pro (propylene) gas cylinders with a CGA-600 connection.

No, the STK-31 is a manual ignition torch. You will need a separate striker or lighter to ignite the flame.

Yes, the STK-31 features a 360-degree swivel tip, allowing you to rotate the tip to reach difficult angles without moving the gas cylinder.

Extreme Swirl technology creates a swirling, high-velocity flame that wraps around the pipe, providing better heat transfer and faster soldering or brazing times.

Yes, the ST-3 tip is replaceable. The handle (regulator) uses a quick-disconnect or threaded system compatible with other STK series tips.

The STK-31 is designed with easy-to-clean orifice screws. You can remove the screw to access and clean the orifice, ensuring consistent gas flow.

Capacity depends on the fuel used. With MAP-Pro, the ST-3 tip can typically silver braze up to 1-inch copper pipe and soft solder up to 3-inch copper pipe.

No, the gas cylinders are sold separately. The product includes the torch tip and regulator assembly only.
