SF₆ Cylinder Supplier — traceable cylinders for every SF₆ duty
As an SF₆ Cylinder Supplier, REAL GAZ looks after both halves of the product: the sulfur hexafluoride itself and the pressure vessel that carries it. Because SF₆ is liquefied inside the cylinder, wall thickness, filling ratio and valve condition matter as much as the gas quality.
Every cylinder is inspected, cleaned and dried before filling, and it leaves with a label that links back to its fill record.

Our cylinders follow ISO 9809, EN 1964 and TPED requirements, and gas analysis is performed in the spirit of ISO 17025, for industrial and laboratory customers.
🏭 Where SF₆ Cylinders Are Used
- ⚡ Utility substations — field crews carry 40 litre and 50 litre cylinders to refill switchgear bays and gas-insulated lines on site;
- 🔧 Equipment manufacturers — factory filling lines use cylinders and manifolds to charge new breakers before shipment;
- 🔬 Laboratory benches — smaller cylinders feed leak detectors, dielectric test cells and gas chromatographs;
- 🏗️ Service workshops — recovery and refilling units draw SF₆ from standard cylinders during overhauls.
💡 Why Choose REAL GAZ as Your Cylinder Source
- ✅ Inspected vessels — periodic test dates, valve threads and neck rings are checked before every fill;
- 🧪 Dry cylinders — evacuation and drying remove moisture that could degrade insulation performance;
- 🎯 Correct valve outlets — outlet connections are matched to the regulators and recovery carts used in your country;
- 🔒 Controlled filling — each fill weight is recorded so that overfilling of the liquefied gas is avoided;
- 📄 Certificate of Analysis (CoA) — supplied with every order
🔬 Quality Control & Safety
- visual and hydraulic test status verification;;
- vacuum drying and purge before filling;;
- weighing against the permitted filling ratio;;
- leak testing of valve, plug and neck area.
Cylinders must be stored upright, secured, shielded from heat above 50 °C, and kept in ventilated areas because SF₆ vapour collects at floor level.
Transport complies with ADR / UN rules for UN 1080 and relevant EN/ISO standards.
📦 Cylinder Sizes & Handling
Choosing the correct vessel affects safety and cost. A 10 litre cylinder suits a laboratory bench, while a 40 litre or 50 litre cylinder is the usual choice for field maintenance. Liquefied SF₆ must never completely fill the cylinder, because liquid expands strongly when warmed, so the filling ratio is controlled by weighing every vessel.
- use a trolley or cradle rather than rolling cylinders on the floor;
- keep valve caps on during storage and transport;
- record cylinder numbers when exchanging empties;
- return cylinders with a small residual pressure to prevent contamination.
Cylinder history matters for audits. REAL GAZ keeps the inspection date, last fill and customer of every vessel, and this record lets us trace any cylinder if a question arises months after delivery. Rental arrangements are available for customers who prefer not to own cylinders.
