PVC Twin welding hose is a premium twin-line welding hose featuring a flame-resistant and oil-resistant tube and cover. The red line is compatible with commonly used fuel gases, including acetylene, hydrogen, natural gas, propane, and propylene, and the blue line is compatible with oxygen.It is designed to deliver gases, typically oxygen and fuel gases such as acetylene, to welding torches and equipment for the purpose of joining metals. PVC twin welding hoses are commonly used in industries such as manufacturing, construction, and metalworking.PVC twin welding hoses are designed to be flame-resistant and are capable of withstanding high temperatures generated during welding processes. They are also resistant to oils, solvents, and other chemicals commonly encountered in welding environments.

Twin Welding hoses are designed for oxyfuel gas welding applications, with color-coded hoses in twin and single configurations for fuel gas (acetylene, hydrogen, natural gas, propane, and propylene), oxygen, and inert gases.The oxygen hose in a PVC twin welding hose is typically colored green, while the fuel gas hose is colored red. This color-coding helps ensure proper connection and prevents the accidental mixing of gases, which could result in hazardous situations. It is crucial to always connect the green oxygen hose to the oxygen supply and the red fuel gas hose to the appropriate fuel gas source.PVC twin welding hose is a specialized hose used in welding applications to deliver oxygen and fuel gases to welding torches and equipment. These hoses are constructed from PVC and are designed to be flame-resistant and capable of withstanding high temperatures. When using PVC twin welding hoses, it is crucial to follow safety guidelines, properly connect the hoses to the correct gas sources, and conduct regular inspections and maintenance.

Frequently Asked Questions
What is a PVC twin welding hose?
A PVC twin welding hose consists of two color-coded parallel hoses joined together — one for oxygen (blue or black) and one for fuel gas such as acetylene or LPG (red or orange) — used in oxy-fuel welding, cutting, and heating applications.
What gases is it suitable for?
The twin welding hose is suitable for oxygen, acetylene, LPG (propane/butane), and hydrogen depending on the hose specification. Always match the hose grade and compound to the specific gas being used.
What is the maximum working pressure?
Typically rated at 200–300 PSI (14–21 bar) for each tube individually. The burst pressure is a minimum 4× working pressure as per welding hose safety standards.
How are the two hoses identified?
Oxygen hose is typically colored blue (international) or black (some markets), and the fuel gas hose is red or orange. Fittings are right-hand thread for oxygen and left-hand thread for fuel gas to prevent accidental cross-connection — a critical safety feature.
What sizes are available?
Available in 3/16 inch (5 mm) and 1/4 inch (6.3 mm) inner diameters — the two standard sizes for welding hose. Standard lengths are 5 m, 10 m, and 20 m with custom lengths for OEM supply.
Does the PVC welding hose meet international safety standards?
Sunhose PVC twin welding hose is manufactured to meet international safety standards for welding hose. Please specify the required standard (ISO 3821, EN 559, etc.) for your market when requesting a quotation.
What is the minimum order quantity?
Standard MOQ is 1,000 meters (measured as total twin hose length). Contact our sales team for pricing and documentation requirements.
