Nitrogen/Argon/Helium/Hydrogen/Air Regulator — one regulator family for five common cylinder gases
The Nitrogen/Argon/Helium/Hydrogen/Air Regulator range from REAL GAZ covers inert, light and compressed-air duties with correctly threaded outlets for each gas. Nitrogen, argon, helium and air are non-flammable, while hydrogen is flammable and needs a left-hand thread outlet, so we match the connection to the gas rather than offering a one-size-fits-all part.
Brass bodies suit general duties, and stainless steel diaphragm versions are available for high-purity work where air ingress and contamination must be kept to a minimum.

Regulators follow EN ISO 2503 and EN ISO 10524-2 principles, with cylinder connections to DIN 477 or CGA patterns depending on the market, for industrial and laboratory use.
Selecting a regulator starts with the gas. Helium and hydrogen have small molecules and leak through poor seals, nitrogen and argon are heavier and forgiving, and compressed air may carry moisture. Outlet range matters too: a chromatograph needs a few bar with fine control, while a pneumatic tool needs far higher flow. Our advisers compare your cylinder pressure, typically 150 to 200 bar, with the required working pressure and flow, and then recommend the body material, gauge scale and diaphragm type. This avoids paying for features that you do not use and prevents under-specified parts.
🏭 Where Multi-Gas Regulators Are Used
- 🧫 Laboratory gas supply — nitrogen and helium carrier flows for gas chromatographs and sample preparation;
- 🏭 Industrial purging — nitrogen or air for blanketing, pressure testing and line blow-out;
- ⚡ Energy and electronics — hydrogen and helium for generator cooling, annealing and leak-detection tasks;
- 🍾 Food and beverage — nitrogen for dispensing and packaging under a controlled outlet pressure.
💡 Why Choose REAL GAZ
- ✅ Right outlet per gas — gas-specific connections prevent a regulator being fitted to the wrong cylinder;
- 🧪 Wide pressure choice — outlet ranges from low laboratory pressures to higher process pressures are available;
- 🎯 Material options — brass for general use and stainless steel where corrosion resistance or cleanliness matters;
- 🔒 Safe hydrogen handling — hydrogen versions carry the correct thread and are supplied with advice on ventilation and leak checks.
- 📄 Certificate of Analysis (CoA) — supplied with every order of gas; regulators ship with product documentation.
🔬 Quality Control & Safety
- each regulator is cleaned and inspected before packing;
- outlet pressure and lock-up are verified on a test bench;
- gauges are checked for zero and range;
- leak testing with inert gas confirms seat and seal integrity, and hydrogen units are never tested with air.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
