Acetylene Hose Cellfast 9×3 mm, 50 m — welding gas hose

Acetylene hose Cellfast 9×3 mm, 50 m is a flexible welding gas hose designed to safely transport acetylene from the supply cylinder to the torch. The hose features an inner diameter of 3 mm and an outer diameter of 9 mm with a continuous 50 metre length, offering sufficient reach for workshop and site welding tasks. Constructed for durability and routine handling, this hose is intended to provide a stable, low-permeability conduit for acetylene gas during cutting and welding operations.

Advantages

The hose is engineered for flexibility and resistance to kinking, which helps maintain consistent gas flow during movement. Robust outer cover material protects against abrasion and light mechanical damage while remaining pliable for coiling and storage. The consistent internal bore supports predictable pressure characteristics and reduces the risk of flow restriction. Its 50 m length reduces the need for extensions and additional couplings in medium to large work areas.

Suitable for

• Oxy-acetylene welding and cutting setups in workshops and garages
• Portable torch work where a long, uninterrupted hose run is required
• Routine fabrication and maintenance tasks involving acetylene gas

Key specifications

• Inner diameter: 3 mm
• Outer diameter: 9 mm
• Length: 50 m
• Material: flexible gas hose construction with abrasion-resistant outer cover
• Intended medium: acetylene gas

How to use

Before use, inspect the hose along its full length for cuts, deep abrasions, or signs of brittleness. Install using compatible fittings and clamps rated for acetylene service; ensure connections are tight and leak-free. Route the hose to avoid sharp edges, excessive heat sources, and pinching points. When in use, secure the cylinder and regulator, open valves gradually and perform a leak test with approved leak-detection fluid or soapy water. After work, depressurize the system following standard oxy-acetylene safety procedures and coil the hose without sharp bends for storage.

Recommendations

Use the hose only for acetylene as specified and within the working pressures and temperatures appropriate for oxy-acetylene systems. Replace the hose if you detect persistent leaks, deep damage, or loss of flexibility. Store the hose in a dry, shaded area away from direct sunlight and sources of oil or solvent contamination.
