The Hi Lo TT 6mm Flashback Arrestor is a crucial safety device designed to safeguard you from a potentially dangerous situation: flashbacks. A flashback occurs when a flame travels back through the fuel gas line, towards the source. This can lead to an explosion, causing serious injury or property damage.

The Hi Lo TT 6mm Flashback Arrestor acts as a barrier, effectively stopping the flashback in its tracks. It’s a small investment that can make a big difference in your safety.

  • Suitable for fuel gas and oxygen applications: The Hi Lo TT 6mm Flashback Arrestor offers versatility for various welding projects
