ACETYLENE HOSE RED ISO 3821 — fuel-gas hose assemblies for torches and manifolds
The Acetylene Hose Red ISO 3821 from REAL GAZ is supplied by the metre or as a finished assembly with crimped nipples, ready to connect between acetylene regulator and torch.
The red cover marks it as a fuel gas line, and the left-hand fittings keep it from being joined to an oxygen outlet.

🏭 Where Red ISO 3821 Acetylene Hoses Are Used
- 🏭 Acetylene manifolds — pigtails between cylinders and a manifold header are built from red hose with matched end fittings;
- ⚙️ Machine cutting — automatic profile cutters take acetylene via long red hoses;
- 🚢 Shipbreaking and repair — heavy-duty hose lengths reach from deck to work area;
- 🔬 Training centres — welder-training schools use standard red hose for demonstration and test work.

📐 Selection Guide
- choose 6.3 mm bore for light torches and 8 to 10 mm for machine cutting;
- request assemblies with a flashback arrestor adaptor if required;
- specify total length including bend allowance.
📦 Supply and Handling
Finished assemblies are given a test tag showing the date, the pressure used and the inspector reference, giving a simple record for site audits. Customers who run many cylinder positions can order assemblies in batches of identical length, which makes replacement quick and keeps spares interchangeable. The assembly can be fitted with a union nut for the regulator end and a torch-side nut for the opposite end, in the thread sizes required by your equipment. If a specification sheet is needed for tender documents, our team will prepare one on request. Lead times for standard lengths are confirmed when you place the order, and technical drawings can be shared before production starts.
🔬 Quality Control & Safety
- pull-off testing of crimped fittings;
- pressure test at 1.5 times working pressure on samples;
- visual inspection of cover and bore;
- leak testing and pressure integrity checks.
Store hoses coiled loosely away from sunlight, oil and sharp edges, and inspect them before each shift. Products and cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
