Acetylene hoses used with oxyacetylene equipment are which color?

Color coding is used on welding gas hoses so you can quickly tell which gas is flowing and avoid dangerous mix-ups. For oxyacetylene setups, the hose that carries acetylene is colored red, while the hose for oxygen is typically green. The red color signals a flammable fuel gas, helping prevent connecting the wrong hose to a regulator or torch. Other colors like blue or yellow aren’t the standard for acetylene in common practice, since green is reserved for oxygen and the red color distinguishes the acetylene line.
