ISO CONNECTOR — standardised cylinder connections for safe gas transfer
An ISO connector from REAL GAZ joins a gas cylinder valve to a regulator, hose or manifold through a dimensionally standardised outlet, so that the right equipment meets the right gas every time.
Each connector is machined from brass or stainless steel, cleaned for oxygen service where required and pressure tested before dispatch.

Our connectors follow ISO 5145 for valve outlets, ISO 10297 for cylinder valves and ISO 2503 for regulator interfaces, for industrial and laboratory use.
🏭 Where ISO Connectors Are Used
- ⚙️ Welding shops — connect oxygen and acetylene cylinders to regulators with a gas-specific thread that prevents mismatched fittings;
- 🔬 Analytical laboratories — link carrier and calibration gas cylinders to chromatographs through leak-tight stainless fittings;
- 🏥 Hospitals and clinics — adapt cylinder outlets to regulators and flowmeters in line with local medical gas conventions;
- 🚀 Aerospace test benches — feed nitrogen and helium to pressure rigs through repeatable, torque-controlled joints.
💡 Why Choose REAL GAZ
- ✅ Standard-compliant geometry — outlet threads and sealing faces are cut to the relevant standard rather than approximated;
- 🧪 Material choice — brass, nickel-plated brass and 316 stainless steel are available to suit the gas and its purity;
- 🎯 Right-gas matching — left-hand and right-hand threads and different diameters stop fuel and oxidant fittings being swapped;
- 🔒 Traceable batches — each production lot carries a reference so that a connector can be traced back to its inspection record;
- 📄 Certificate of Analysis (CoA) — supplied with every gas order that accompanies your connectors.
🔧 Selection & Handling Notes
- Seal inspection — check the washer or gasket before each fitting and replace it if it is flattened, cracked or contaminated.
- Hand tightening — tighten with the correct spanner only and never use PTFE tape on a metal-to-metal seal.
- Storage — keep spare connectors capped in clean bags so that dust and oil do not reach the sealing face.
📦 Supply & Ordering Guidance
When ordering, please state the gas, the cylinder valve standard and the equipment you wish to connect. We confirm whether a DIN, BS, CGA or NF outlet is needed, and we can supply the connector with a matching regulator so that the whole set arrives tested together. Orders can be placed for a single replacement part or for scheduled quantities, and our logistics team arranges cylinders and fittings on the same vehicle where possible, which reduces handling and administration for your purchasing department.
🔬 Quality Control & Safety
- ultrasonic cleaning and degreasing of every wetted part;
- thread gauge inspection of each outlet and nut;
- helium leak testing of sealing faces;
- pressure integrity checks above working pressure.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
