591F71 - ESAB Grade T Twin Welding Hose 3/16" x 12.5' (A-B Fittings)

ESAB Grade T Twin Welding Hose (3/16" ID x 12.5 ft)

The ESAB 591F71 is a specialized premium twin welding hose designed for versatility and specific equipment configurations. Manufactured to Grade T specifications, this hose is engineered with a high-quality synthetic rubber liner and cover that makes it safe for use with all fuel gases. Unlike Grade R hoses which are restricted to Acetylene, Grade T hoses resist the chemical degradation caused by alternate fuels such as Propane, Propylene, Natural Gas, and MAPP gas, while remaining perfectly safe for Acetylene use. This makes it a universal solution for shops utilizing multiple fuel types.

A key technical feature of this specific SKU is its fitting configuration. It is terminated with "A-B" connections, meaning one end features A-Size (3/8"-24 UNF) nuts, typically found on light-duty, precision, or aircraft-style welding torches, while the other end features standard B-Size (9/16"-18 UNF) nuts, which fit the vast majority of industrial gas regulators. This eliminates the need for additional brass adapters, reducing leak points and weight at the torch end.

With a 3/16-inch inner diameter, this hose is lightweight and extremely flexible, minimizing operator fatigue during fine detail work. The 12.5-foot length is specifically tailored for bench-top applications or stationary setups where long, heavy hoses would be cumbersome and create tripping hazards. The hose is flame and oil resistant, ensuring longevity in harsh industrial environments.
