PVC Twin Welding Hose

PVC twin welding hoses are specialized hoses designed for oxy-acetylene welding and cutting applications. These hoses are constructed to withstand the specific conditions associated with welding operations, where oxygen and acetylene gases are used for various processes such as cutting, welding, and brazing.


  • Material:
    • PVC twin welding hoses are made from polyvinyl chloride (PVC), a durable and flexible thermoplastic material.
  • Inner Tube:
    • The inner tube of the hose is designed to handle both oxygen and acetylene gases. It is often made from a material resistant to the chemical properties of these gases.
  • Reinforcement:
    • Twin welding hoses typically have reinforcement layers, such as braided or spiraled synthetic fibers, to provide strength and durability.
  • Color Coding:
    • To differentiate between the hoses carrying oxygen and acetylene, PVC twin welding hoses often have distinct color-coding:
      • Red Hose: Used for acetylene.
      • Green Hose: Used for oxygen.
  • Size Range:
    • PVC twin welding hoses come in various sizes to accommodate different flow rates and welding applications.
  • Pressure Rating:
    • These hoses are designed to handle specific pressure levels associated with oxy-acetylene welding. The pressure ratings for the oxygen and acetylene hoses may differ to prevent mixing of the gases.
  • Flexibility:
    • PVC twin welding hoses are flexible, allowing for easy handling and maneuverability in welding operations.
  • Temperature Resistance:
    • The hoses are designed to withstand the high temperatures generated during welding processes. They are also resistant to the heat produced by the gases.
  • Kink Resistance:
    • Some PVC twin welding hoses are engineered to resist kinking, ensuring a continuous and unobstructed flow of gases during welding operations.
  • Fittings:
    • The hoses are equipped with fittings suitable for connecting to welding equipment, regulators, torches, and other components of the oxy-acetylene system.
  • Abrasion Resistance:
    • PVC twin welding hoses are often constructed to resist abrasion, as they may come into contact with rough surfaces during welding operations.
  • Compliance Standards:
    • These hoses must comply with relevant safety standards and regulations for welding equipment. Ensuring compliance helps maintain a safe working environment.
