The Hi-Lo GT Flashback Arrestor is your essential torch-side safety device, engineered to prevent a potentially catastrophic event: flashback. A flashback occurs when a combustible gas mixture travels backward from the torch tip into the fuel or oxygen lines. This can lead to an explosion, causing severe injuries and equipment damage.


  • Double Block & Bleed: Featuring a non-return valve and a flame arrestor, the Hi-Lo GT acts as a double block, stopping flashback in its tracks. Even if flames reach the device, the flame arrestor extinguishes them, while the non-return valve prevents further gas flow.
  • Built to Last: Constructed with robust brass components, the Hi-Lo GT is designed to withstand the demanding environment of welding applications. Its durability ensures long-lasting performance and peace of mind.
  • Contamination Defence: A built-in dust filter safeguards the internal components from contaminants that could compromise performance. This translates to reliable operation and uninterrupted welding sessions.
  • Easy Maintenance: The Hi-Lo GT is designed for user-friendliness. Regular inspection and maintenance are crucial for optimal safety, and this device simplifies the process.
