MULTI-FUNCTION O2 FLASHBACK ARRESTOR — several safeguards in one oxygen device
A multi-function O2 flashback arrestor from REAL GAZ brings several safeguards into a single body, which reduces the number of fittings on the hose and the number of joints that can leak.
The usual functions are a sintered flame arrestor, a spring-loaded non-return valve and a thermally or pressure-activated cut-off that closes the line if a flashback has already heated the device.

Arrestors follow ISO 5175-1 and EN 730-1 principles, while threads and connections correspond to EN 560 practice for gas welding equipment.
Installation is straightforward but must follow the maker's instructions. Fit the arrestor so that the arrow on the body matches the gas flow, tighten with the correct spanner and test the joints with a leak-detection fluid. Many users place one unit at the regulator outlet and another at the torch inlet, which gives two independent barriers. Check the unit at set intervals, usually at every cylinder change, and replace it after any flashback or after the period recommended in the user instructions. Keep spare units in stock so that a damaged part never tempts anyone to continue without protection.
🏭 Where Multi-Function Oxygen Arrestors Are Used
- ⚙️ Mobile welding trolleys — one compact unit per hose keeps a trolley tidy and makes daily inspection quicker;
- 🔧 Site repair crews — maintenance teams working away from a workshop value a device that protects against flame, reverse flow and overheating at once;
- 🏭 Production bays with shared supply — where many torches draw from one oxygen line, point-of-use arrestors prevent an incident at one station from spreading;
- 🛠️ Pipeline and boiler maintenance — long working hours and awkward hose routing increase the chance of kinks and blocked tips, so extra protection is sensible.
