Harris flashback arrestor is a safety device used in oxy‑fuel welding, cutting, brazing, and related gas systems to prevent dangerous flashback events from traveling back through hoses and regulators to the gas cylinders. � Made by Harris Products Group (often branded as FlashGuard®), these arrestors are widely used in workshops, fabrication shops, and industrial gas distribution systems to protect people, equipment, and facilities. �
What is a flashback and why it matters
In oxy‑fuel processes, a “flashback” occurs when the flame propagates backward from the torch tip into the mixing chamber, hose, or even the regulator and cylinder. � This can happen due to incorrect gas pressures, blocked tips, damaged hoses, or improper shutdown sequences. � If unchecked, a flashback can cause hose fires, equipment damage, explosions, or serious injury. � A flashback arrestor is designed specifically to stop this reverse flame and gas flow before it reaches critical components.
