Cylinder Flashback Preventer №2 for Laboratory — reverse-flow protection for laboratory cylinder lines
The Cylinder Flashback Preventer №2 for laboratory use is a small-bore protective fitting for cylinders that feed burners, furnaces and combustion experiments. REAL GAZ supplies it with a miniature flame arrester and a low-pressure check valve.
It is sized for the low flows common to research benches rather than for heavy industrial cutting.
It is sized for the low flows common to research benches rather than for heavy industrial cutting.
Selection draws on ISO 17025 laboratory practice, EN ISO 2503 regulator interfaces and EN 1089-3 cylinder colour coding, suitable for teaching and research laboratories.
In a laboratory, gas lines are frequently changed for new experiments, so protective devices must be easy to fit and inspect. We recommend labelling each line with the gas name and the date of the last check, keeping cylinders in a ventilated store and using only the minimum pressure needed at the burner. Where oxygen and fuel gases are used together, keep both preventers close to the cylinders and use hoses of different colours. Our team can supply matching regulators for 1/4 inch and 6 mm tubing, together with pure gases, calibration mixtures and leak-detection fluid for your daily routines. Teaching laboratories can request a starter set for each bench, containing a preventer, a short hose, clamps and a laminated instruction card, so that demonstrations begin with the right equipment and every student sees the same safe practice.
🏭 Where Cylinder Flashback Preventers №2 Are Used

📦 Laboratory Use Notes
- fit one unit on each gas line, not only on the fuel line;
- use flexible hose rated for the gas and keep it as short as practical;
- inspect before each experiment series and replace on any sign of damage;
- keep cylinders secured away from burners and heat sources.
