A twin hose is a type of hose used in various applications, primarily in welding and cutting operations, where two separate fluid lines are needed in one combined assembly. Typically, a twin hose consists of two parallel hoses that are often bonded together, with each hose serving a different function. One hose is used to carry the fuel gas (e.g., acetylene), while the other carries oxygen or another oxidizing gas for welding or cutting tasks. The two hoses are color-coded for easy identification—usually red for fuel gas and green for oxygen.
Twin hoses are commonly used in oxy-fuel welding and cutting, and they are designed to withstand high pressures and temperatures. They are flexible, durable, and often constructed with materials that provide resistance to abrasion, wear, and chemical damage. Twin hoses ensure that the welding or cutting process is supplied with both fuel and oxygen simultaneously, making them essential for various industrial applications such as metalworking, construction, and automotive repair.
