Five safety functions


  • Check valve shuts off gas flow in case of back pressure.

  • Backflow valve closes off gas backflow.

  • Flame damper stops and extinguishes penetrating flashbacks.

  • Thermic cut-off will shut off gas flow if temperature becomes too high (over 95°C).

  • Quick and easy to reprime, no need to remove hose pressure.


  • 30° outlet connection; the flashback arrestor is connected with the gas cylinder's pressure regulator, leaving welding hoses in line with the gas cylinder.

  • When the flashback arrestor is primed and ready, the colour-coded (for the gas used) lever is concealed inside the device's frame.

  • In the event of a backlash, the lever pops out and the gas flow stops.

  • Retuning is easy by pressing the lever back inside the body of the device.

  • Hose pressure does not need to be removed for retuning.

  • Installed on gas cylinder pressure regulators and gas network intake points.

  • Backlash guards must be used whenever fuel gases and oxygen are used simultaneously in the combustion equipment.

  • Designed and tested for: acetylene, hydrogen, propane (LPG), methane (natural gas), MAP gases and oxygen.

  • Manufactured according to EN 730-1.

  • Compliance has been verified by an external organisation (BAM).
