0386-1090 - TurboTorch AH-12 Acetylene Hose, 12 ft, Grade R, A-Fittings

Technical Overview of the TurboTorch AH-12 Acetylene Hose

The TurboTorch AH-12 (SKU: 0386-1090) is a specialized single-line gas hose engineered specifically for air-acetylene applications. Manufactured to Grade R specifications, this hose is compatible strictly with acetylene fuel gas and is not suitable for use with propane or MAPP gases, which require Grade T hoses due to oil resistance requirements. The hose features a 3/16-inch internal diameter (I.D.), which provides the necessary flow rate for standard soldering and brazing operations found in plumbing and HVAC workflows without adding unnecessary weight or bulk to the torch assembly.

A critical technical distinction of the AH-12 is its termination points. Both ends are fitted with Female "A" size fittings, utilizing a 3/8"-24 thread pitch. These are Left-Hand (LH) threads, adhering to industry safety standards for fuel gases to prevent accidental connection to oxygen or inert gas lines. The "A" fitting size is smaller than the standard "B" fittings (9/16"-18) typically found on heavy-duty oxy-fuel rigs, making this hose exclusively compatible with the compact regulators and torch handles of the TurboTorch and Sof-Flame series. The fittings are swaged securely, and the assembly includes external reinforcement sleeves at the crimp points. These sleeves significantly reduce the bend radius stress at the connection, mitigating the risk of leaks or ruptures in these high-fatigue zones.

The hose is constructed from durable, color-coded rubber that maintains flexibility across a range of working temperatures. The 12-foot length offers a balance between portability and reach, allowing operators to maneuver around equipment and fixtures effectively. As a genuine OEM component, the AH-12 ensures compliance with the original equipment specifications of TurboTorch outfits, guaranteeing a leak-free seal and reliable performance under the pressure parameters of air-acetylene systems.
