PROPANE FLASHBACK ARRESTOR — dependable protection for LPG cutting and heating
A Propane Flashback Arrestor from REAL GAZ is designed for the specific flame speed and pressure of propane and LPG mixtures. It stops flames, prevents reverse flow and, in many models, cuts the gas off when overheated.
Propane burns with oxygen at a lower speed than acetylene, but flashbacks still happen, especially with worn hoses and poorly adjusted torches.

Arrestors meet ISO 5175-1 and EN 1256 hose-assembly practice, suitable for roofing and cutting work.
🏭 Where Propane Flashback Arrestors Are Used
- ⚙️ Oxy-propane cutting — protect steel-cutting torches in scrap yards and fabrication halls;
- 🔬 Roofing and bitumen work — guard portable burners used outdoors where gas hoses may be damaged;
- 🏥 Heating and bending — help control ductwork, pipe bending and thawing tasks;
- 🚀 Food and catering equipment — protect burners fed by LPG bottles in kitchens and workshops.
💡 Why Choose REAL GAZ

- 🔒 Weather resistance — sealed bodies perform in outdoor conditions;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- propane flame-return testing;
- gas flow and pressure-loss measurement;
- leak testing at working pressure;
- visual and thread inspection.
Keep propane cylinders upright and tightly secured, and check hoses regularly. Cylinders follow ADR / UN rules and relevant EN/ISO standards.
Practical use with LPG: propane is heavier than air and collects in low spots, so leaks near floors, trenches or vehicle pits create a real hazard. Use soapy water or approved detection fluid to check every joint after fitting the arrestor, and never use a naked flame for the test. Keep hoses short, protected from sparks and away from hot metal, and replace them at the first sign of cracking. Because propane needs a large amount of oxygen to burn, pay special attention to correct oxygen pressure for cutting, and check that the arrestor on the oxygen side is also suitable for the connected equipment. Do not use propane arrestors on acetylene or hydrogen lines, and do not place hoses where vehicles or trolleys can crush them. Replace any arrestor that shows rust, cracks in the body or a stiff valve, and store spares in a clean, dry box away from heat.
