The Victor Flamebuster Plus FB-O (0657-0010) is a critical safety device designed for professional oxy-fuel cutting and welding applications. Engineered to mount directly to the torch handle, this unit provides a dual-layer of protection by combining a reverse flow check valve with a flashback arrestor. This configuration is essential for preventing the dangerous mixing of gases in the hoses and stopping flame propagation in the event of a flashback. The device is specifically calibrated for Oxygen service and features standard "B" size 9/16"-18 Right Hand (RH) connections, ensuring compatibility with the vast majority of industrial torch handles.
In industrial environments, flow capacity is a significant concern when adding safety devices. The FB-O is a "Heavy Duty" rated arrestor, designed to maintain sufficient flow rates for large heating nozzles and cutting tips without starving the flame. The internal mechanism utilizes a sintered stainless steel filter that effectively quenches flames before they can travel upstream into the hose or regulator. Simultaneously, the spring-loaded check valve prevents the backflow of fuel gas into the oxygen line, addressing one of the primary causes of flashbacks. The brass construction ensures durability and resistance to the harsh conditions typical of fabrication shops and construction sites.
Victor recommends the use of these devices whenever possible to meet safety standards and protect both the operator and the equipment. While regulators often have built-in arrestors, torch-mounted units like the FB-O offer the last line of defense closest to the point of ignition. This proximity is crucial for minimizing the volume of mixed gas available to explode in the event of a flashback. The unit is color-coded (typically green label or markings) and threaded specifically for oxygen to prevent cross-connection errors during setup.
