What color are acetylene hoses?

Acetylene hoses are universally color-coded in red to ensure safety and proper identification during use. These color codes are established to prevent confusion when working with different gases, which is crucial in environments where multiple gas types may be present. Since acetylene is a highly flammable gas, the red color serves as a clear visual indicator, reducing the risk of accidents that could arise from mistakenly using the wrong hose for a gas.

Each color assigned to gas hoses—a standard practice in the industry—corresponds to specific gases used in welding and brazing applications. Knowing the correct color coding helps welders and technicians quickly identify which hoses to connect to specific equipment and ensures compliance with safety regulations. Understanding these designations is essential for anyone involved in brazing, welding, or related trades, as it reinforces safe handling practices and enhances overall workplace safety.
