Protect yourself and your workspace with the Hi-Lo Resettable DS2000 Flashback Arrestor, available for both Oxygen and Fuel Gas. This essential safety device acts as a multi-layered shield against the dangers of flashbacks, offering peace of mind and enhanced control during welding, brazing, cutting, and other gas applications.


  • Resettable Pressure-Sensitive Gas Cut-Off: Instantly stops gas flow in case of pressure surges, preventing explosions and equipment damage
  • Flame Barrier: Quenches flames within the arrestor, preventing them from traveling back to the source
  • Thermal Shut-Off Valve: Triggers an automatic shut-off when excessive heat is detected, safeguarding against hose burn-through
  • Gas Non-Return Valve (Check Valve): Blocks the flow of gas back into the regulator, eliminating the risk of dangerous gas mixtures
