This VEVOR Oxygen Acetylene Hose is a 25 ft 1/4-inch T-grade twin hose designed for welding, soldering, brazing, and cutting applications. It supports a 300PSI working pressure and a 900PSI bursting pressure, helping provide stable, high-pressure resistance for torch-ready setups. Built with a durable, flexible rubber construction that resists kinks and tangles, the hose features a 3-layer structure: a wear-resistant rubber outer layer, a high-strength fiber middle layer, and a durable rubber inner layer. This layered design is intended to help improve wear resistance for long-lasting performance in industrial and workshop use. For safer and more efficient gas handling, the hose uses a clear color-coding system: the green hose is for oxygen, while the red hose is for acetylene, propane, or other fuel gases. With 9/16"-18 LH/RH B fittings, it is compatible with oxygen/acetylene and other listed fuel gases for auto shops, factories, and repair shops.
