Twin Welding Hose
Twin welding hose, also known as Twin line welding tube, is used in welding applications. It consists of two colored hoses connected to connect the welder to oxygen/acetylene welding supply. Commonly used inside diameter is 1/4 inch and length is 50 feet. As a factory, we can customise the I.D. and length you need.
Temperature range: -40ยฐF to 120ยฐF (-40ยฐC to 49ยฐC)
Structural Tube: EPDM synthetic rubber
Cover: EPDM synthetic rubber, Blue/green/red, smooth, synthetic rubber
Reinforcement:High strength synthetic yarn braiding
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 difference between Grade R & Grade T Twin Welding Hose?
Grade R: It is designed and recommended for both acetylene and oxygen. Until about 15 years ago, it was the only grade of Twin Welding Hose available. It is not recommended for use with LPG, propane, natural gas or propylene. The reason propane is not recommended is that the oil in propane will eventually dry rot the hose. This usually takes about 1 year to occur. The surface of the hose will crack and lose its flexibility. This can be a very unsafe condition and requires immediate replacement of the hose. Class R hose is not unsafe from the start, but it will have a shorter life. Hose longevity is important to some cutters and welders and not to others. R-rated double-welded hose is cheaper, which means a lot to some users. Regardless of the grade, their hose usually won't last a year.
Grade T: Grade T double-welded hose is designed for use with alternative fuels such as LPG, propane, natural gas and propylene. However, it can also be used with acetylene. It is more expensive than Grade R because it resists the effects of oil in propane. Although T-rated can be used with โall gasesโ, it is recommended to change the hose when switching between acetylene and alternative gases. This is because residual oil in propane can seep into the pores of the hose.
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.
