Argon Nitrogen Helium Regulator — safe pressure control for the three main inert gases
An Argon Nitrogen Helium Regulator from REAL GAZ is built for gases that do not react, which means it can use proven brass or stainless bodies with long-lasting seats.
Helium needs special attention because its small atoms escape through poor seals, so our regulators are leak-tested accordingly.

REAL GAZ supplies this regulator according to EN ISO 2503, ISO 5145 and ISO 10524-1, suitable for industrial and scientific use.
These three gases are chemically inert but behave differently in practice. Argon is heavier than air and can collect in low areas, nitrogen is lighter than air yet can still displace oxygen in enclosed spaces, and helium rises quickly and escapes through the smallest leaks. For safety, install oxygen monitors in rooms where large cylinder volumes are stored, keep cylinders upright and chained, and always ventilate before entering a confined space after purging. Typical regulator ranges are 0-4, 0-10 and 0-16 bar outlet with 200 or 300 bar inlet, and the cylinder outlet is normally DIN 477 No. 6 or No. 10 depending on pressure. We also provide cylinders in 5.0 and 6.0 purities, helium for leak detection and argon-based mixtures for welding and calibration. Our drivers and warehouse staff are trained in safe cylinder handling, and every delivery includes the safety data sheet for the gas supplied.
🏭 Where Argon, Nitrogen and Helium Regulators Are Used
- ⚙️ Cryogenic and MRI service — helium handling needs robust seals and dependable gauges;
- 🔬 Food and beverage packaging — nitrogen flushing keeps products fresh without oxidation;
- 🏥 Metal fabrication — argon shielding supplies TIG, MIG and plasma processes;
- 🚀 Oil and gas testing — inert nitrogen supply is used for pressure tests and line purging.
