TECHNICAL GAS QUICK FITTING — precision fittings for high-purity and specialty gas systems
A technical gas quick fitting from REAL GAZ is built for systems where purity, repeatability and tight sealing matter as much as speed. Fittings are machined to close tolerances and finished so that no oil, burrs or particles are carried into the gas stream.
Stainless steel 316L and nickel-free brass options are available, with PTFE, FKM or EPDM seals to match the gas, the temperature range and the cleanliness class required.

Material and cleanliness choices follow guidance in ISO 9539 for oxygen compatibility and ISO 5145 for outlet selection, supporting research, electronics and process installations.
Typical specifications include working pressures up to 200 bar for gaseous nitrogen and argon, operating temperatures from minus 20 to plus 80 °C for standard seals, and wetted parts that can be supplied degreased for oxygen or ultra-high-purity service.
🏭 Where Technical Gas Quick Fittings Are Used
- 🔬 Gas chromatography — carrier, make-up and detector gases are connected to instruments with minimal dead volume;
- 💻 Electronics and semiconductor support — nitrogen and argon purge lines use fittings that avoid particle shedding;
- 🧫 Food and beverage packaging — modified-atmosphere gas blends are routed to filling machines through demountable joints;
- 🚀 Test facilities — rigs for sensors and flow devices are reconfigured quickly between test campaigns.
💡 Why Choose REAL GAZ
- ✅ Low dead volume — compact internal geometry flushes faster and limits trapped air during purging;
- 🧪 Material choice — 316L steel or brass bodies with seals matched to chemically aggressive or ultra-dry gases;
- 🎯 Repeatable sealing — the connection can be made and broken many times without loss of leak tightness;
- 🔒 Clean assembly — parts are degreased and capped before packing to protect the internal surfaces.
- 📄 Certificate of Analysis (CoA) — supplied with every order where the product is a gas; documentation and traceability details accompany equipment.
📦 Handling & Storage Notes
- Purge a new line with dry inert gas before admitting the process gas;
- Use two spanners when tightening threaded ends so the fitting body is never twisted;
- Record the seal material on the line label so replacements always match;
- Keep fittings in their original caps until the moment of installation.
🔬 Quality Control & Safety
- verification of material certificates for bar stock and seals;
- dimensional control of sealing profiles and thread gauges;
- pressure and helium leak testing on sample units;
- particle-conscious cleaning and bagging for sensitive duties.
Where fittings are fitted to cylinders, those cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
