Flashback Arrestor Gas Cylinder, When more than 15 pounds of pressure is used, acetylene becomes unstable and decomposes explosively. Dec 22, 2025 ยท If flashback arrestors are not fitted, there is a real risk of the explosion travelling through the regulator and into a gas cylinder, with extremely serious consequences. Furthermore, it is the ideal protection at cylinder regulators, distribution lines, tapping points and gas distributors (board connection block). Dry flashback arrestors typically use a combination of safety elements to stop a flashback or reverse flow of gas. Flashback arrestors are key safety components in gas distribution systems and are typically used together with supply, switchover boards, pressure regulators, cylinder valves, and line valves to ensure safe, stable, and reliable gas supply. The fuel gas, being at a higher pressure, can travel up the oxygen line and mix with gas in the hose, regulator and cylinder. Arresters extinguish flames and have a check valve to stop reverse gas flow. SAFE-GUARD-5 / 5 FUNCTION FLASHBACK ARRESTOR from GCE Group, leading manufacturer of gas flow control equipment. WITT flashback arrestors / flame arrestors (FBA) are used to protect single cylinders, outlet points or pipelines and can be used for almost all technical gases such as acetylene, propane, propylene, ethylene, methane, hydrogen or oxygen.
