Specialty Gas R-134A — high purity tetrafluoroethane for precision duties
Specialty gas R-134A is tetrafluoroethane purified beyond refrigerant specification, commonly at 99.99 % or better, with very low moisture, acidity and high-boiling residue.
REAL GAZ offers it for customers who treat the gas as a process material rather than just a coolant.
REAL GAZ offers it for customers who treat the gas as a process material rather than just a coolant.
Gas quality is documented to ISO 17025 laboratory practice, with ISO 817 designation and ADR UN 3159 transport, suitable for analytical and pharmaceutical use.
Typical impurity data cover water, air and other non-condensables, and related fluorocarbons. A batch CoA states the measured values, and customers can request specific analysis if their application is sensitive to a particular contaminant.

⚙️ Trusted Gas Solutions
REAL GAZ delivers specialty gas R-134A to manufacturers and research centres in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA, always with analysis supplied.
To preserve purity, use stainless steel or compatible lines, purge connections before opening the cylinder, and keep the valve outlet capped when not in use. Contamination by air or moisture during connection is the most common cause of out-of-specification results, so we supply connection advice and, on request, dedicated cylinders reserved for one product only.
Beyond the gas itself, we provide the supporting services that high-spec users value: certified analysis, cylinder dedication to avoid cross-contamination, and advice on pressure regulation and sampling. A typical analysis lists purity, water, acidity, non-condensable gases, residue after evaporation and related halocarbons. Customers working in regulated sectors can have their specification attached to the purchase order, so every delivery is checked against agreed limits before leaving our premises. Where required, we can also arrange smaller sample cylinders so that a new supplier or method can be validated before a full purchase order is placed.
