Twin Welding Hose
Twin welding hose, also known as Twin line welding hose, is used in welding applications. It consists of two colored hoses connected to connect the welder to the gas supply.
When the Twin line welding hose is used, red and green are usually used to distinguish the gas used. The red hose is used to transport acetylene gas, and the green hose is used to transport oxygen.
The design of the double-welded soft tube is flexible, and due to the needs of the working environment, it needs to have heat, wear, and chemical resistance.
Twin welding hoses are usually made of rubber or PVC. It is used in various welding applications, including MIG and TIG welding.

What is the purpose of a Twin line welding hose?
Twin line welding hose, also called Twin welding hose, is mainly used to transport oxygen and gas in welding, cutting, and related processes. It consists of two hoses, red and green. The green one delivers oxygen, and the red one provides gas (propane, propylene, hydrogen, etc.). This hose is designed to distinguish between oxygen and gas and can also be delivered to welding equipment simultaneously to achieve efficient and safe welding and cutting.
What is the scope of application of Grade R and Grade T Twin welding hoses?
- Transport
Grade T Twin welding hose can transmit more gas, including propane, propylene, hydrogen, etc.
Grade R Twin welding hose is mainly suitable for conveying acetylene gas. - Application
Grade T twin welding hose has a broader application range and higher safety and is suitable for industrial welding applications.
Grade R Twin Welding Hose is better suited for general welding and cutting, household, and minor engineering projects.
