Welding Hose (Red and Blue)
Welding Hose (Red and Blue) is designed to transfer the gases used in oxy-acetylene welding and cutting equipment. The two colours help operators distinguish the separate gas lines: red for acetylene and blue for oxygen. This identification is important when setting up and maintaining gas-welding equipment.
The hose uses a soft PVC construction reinforced with synthetic yarn braiding between multiple PVC layers. The reinforcement runs in crosswise and longitudinal directions. This construction combines flexibility with the pressure-carrying design required for the specified welding-hose application.
Available in 6 mm, 8 mm, 10 mm and 12 mm internal diameters, Welding Hose (Red and Blue) is relevant to industrial workshops, service workshops, shipbuilding and repair yards, and garages using oxy-acetylene welding or cutting equipment. Buyers should match the selected hose size and pressure rating to their equipment requirements before ordering.
Product Overview
This product is a braided PVC hose intended for oxy-acetylene welding and cutting systems. The red hose is used for acetylene service, while the blue hose is used for oxygen service. Separate colours make the gas lines easier to identify during installation and routine equipment checks.
The hose is available in four published internal-diameter options. Each size has a specified wall thickness and working-pressure rating at 30°C. Standard lengths listed in the product data are 50 metres and 100 metres.

Colour and Gas Identification
Red welding hose
The red hose is designated for acetylene applications in the referenced product information. It forms the fuel-gas line in an oxy-acetylene welding or cutting setup.
Blue welding hose
The blue hose is designated for oxygen service. It forms the oxygen supply line in the same type of equipment.
Do not interchange gas lines based only on a hose’s physical fit. Confirm the gas designation, hose suitability, equipment instructions and applicable safety requirements before connecting the system.
Design and Construction
The hose is constructed from multiple layers of soft PVC with synthetic yarn reinforcement between the layers. The yarn is arranged in both crosswise and longitudinal directions. This braided reinforcement forms part of the hose’s pressure-carrying construction while retaining flexibility for equipment routing.
The supplied product information identifies the material and reinforcement arrangement but does not state a specific PVC grade, yarn composition, outer-diameter tolerance, minimum bend radius or detailed cover formulation. These values should be requested if they are required for an engineering specification or procurement approval.
Connection Options
The supplied product data does not specify factory-fitted end connections, thread standards, coupling types or connector dimensions. Select compatible hose connections and clamps only after checking the welding regulator, torch and equipment manufacturer’s requirements.
If you need a hose assembly with fitted connectors, mention the required end arrangement in your enquiry. Do not assume that a bare hose coil includes fittings or assembled ends.
Working Pressure Information
The listed working-pressure ratings are specified at 30°C and vary with the internal diameter:
- 6 mm ID: 25 kg/cm² at 30°C
- 8 mm ID: 25 kg/cm² at 30°C
- 10 mm ID: 25 kg/cm² at 30°C
- 12 mm ID: 20 kg/cm² at 30°C
These figures are working-pressure values from the supplied product data, not burst-pressure or test-pressure values. The source does not provide a burst-pressure rating, test pressure or pressure-versus-temperature chart. Do not use the working-pressure figures as a substitute for those values.
Applications
Welding Hose (Red and Blue) is intended for gas supply in oxy-acetylene welding and cutting equipment. The published product application information identifies the following working environments:
- Industrial welding workshops
- Metal fabrication and service workshops using oxy-acetylene equipment
- Shipbuilding and ship repair yards
- Garages and vehicle service workshops using gas-welding equipment
- Welding and cutting equipment installations requiring separate oxygen and acetylene lines
Confirm gas compatibility and equipment requirements before using the hose in any particular process. The product information provided does not establish suitability for LPG, propane, argon, nitrogen, fuel transfer, compressed-air service or other gases.
Product Selection Guide
Use the following checks when selecting a welding hose for a new installation or replacement:
- Identify the gas: Select the red hose for acetylene and the blue hose for oxygen as specified for this product.
- Check internal diameter: Choose from the published 6 mm, 8 mm, 10 mm and 12 mm options according to the equipment requirement.
- Verify pressure: Match the working-pressure rating to the required operating conditions. The published values apply at 30°C.
- Confirm coil length: Check whether 50 m or 100 m is suitable for the installation and purchasing requirement.
- Check connections: Verify the required hose-end connections and compatibility with regulators and torches separately.
- Review technical documentation: Request any additional test, temperature or compliance information needed for the application.
Industrial Buyer Guide
For procurement teams, contractors and workshop managers, the correct hose selection should be based on gas service, internal diameter, working pressure and required coil length. Colour alone is not enough to establish compatibility.
When requesting a quotation, provide the required red and blue hose quantities separately, the selected internal diameter, the desired coil length and the intended equipment. If your purchase specification requires a particular certification, temperature range, test pressure or connection arrangement, ask for supporting documentation before approval.
For replacement purchases, compare the existing hose markings and equipment requirements with the published product data. Do not assume that hoses with the same colour or nominal diameter have identical construction or ratings.
