1/4-inch twin welding hose is a double-layers hose made of PVC. It features two parallel tubes, typically color-coded, and may contain internal reinforcement to improve pressure and abrasion resistance. And because of the lightweight, flexible, chemically resistant, and highly resistant to pressure. It can simultaneously transport two gases (such as oxygen and acetylene), making it suitable for gas welding, gas cutting, metalworking, and small welding operations.
Twin Welding Hose Structure
Material: We use 100% new material (polyvinyl chloride (PVC) ) to produce and perform flexibility and durability.
Twin hose design: Consists of two separate hoses placed side by side (twin hose), typically with dual-color markings to distinguish gas types.
Reinforcement: We use high-strength polyester braided reinforcement to increase pressure and abrasion resistance.
Connectors: Typically feature standard threads or quick-release connectors to ensure a secure connection with welding equipment.
Popular Size
For PVC twin welding hose, the popular size is 1/4”(6mm). Here is a detailed specification for your reference:
Inner Diameter: 1/4 inch (approximately 6 mm), suitable for small to medium-sized welding operations.
Wall thickness: Mostly we customized thickness according to customer’s requirement.
Outer Diameter: Varies slightly depending on the reinforcement layer and material. The typically approximately 11-12 mm.
Length: Common standard lengths include 10m, 20m, and 50m. And custom lengths are also available.
Regular Parameters
Hose Pressure:
Maximum working pressure: Typically 15-20bar, so it is sufficient for general oxy-acetylene welding.
Burst pressure: Typically ≥3 times of the working pressure. Aims to ensuring safe use.
Temperature Range:
Applicable temperature: -10°C to +65°C. PVC remains flexible at low temperatures, but may soften at high temperatures.
Gas compatibility:
The hose is suitable for common welding gases such as oxygen, acetylene, etc.
Application Scenarios
The 1/4-inch twin welding hose is widely used in industrial manufacturing, automotive repair and laboratories. It is suitable for low temperature environments, but must avoid high temperatures and mechanical damage to ensure safe use.
Industrial manufacturing: Suitable for metalworking, automotive repair, pipeline installation, and other fields requiring gas welding.
Laboratories and small workshops: Due to its lightweight and easy-to-manage hose, it is suitable for small-scale welding operations.
