25Y29 - TurboTorch G-4 Air-Acetylene Torch Handle

Technical Overview of the TurboTorch G-4 Handle

The TurboTorch G-4 Handle (SKU: 25Y29 / Mfr Model: 0386-0308) is a premium air-acetylene torch handle designed for professional HVAC and plumbing applications. Engineered by ESAB/TurboTorch, this handle is a core component of many B-Tank and MC-Tank torch kits. It features a standard A-size hose connection (3/8"-24 Left Hand threads), ensuring compatibility with a wide range of industrial acetylene hoses.

Technically, the G-4 is built to manage high-temperature brazing and soldering tasks with precision. The rear-mounted control valve allows for fine-tuning of the gas flow, enabling the operator to adjust flame intensity without changing their grip significantly. The handle body is constructed from high-impact materials designed to resist thermal stress and mechanical impact common in job site environments. It is compatible with a variety of TurboTorch tips, including the Extreme and Standard series, provided the correct quick-disconnect or threaded adapter is utilized where applicable.

For maintenance and longevity, the G-4 includes an easy-to-access design for cleaning. The internal gas passages are optimized to maintain consistent pressure from the regulator to the tip, minimizing flame fluctuation. When paired with a B-Tank regulator (CGA 520), this handle provides the reliable heat output required for silver brazing copper pipes, soft soldering, and general heating applications.
