The Victor FBHC-O (SKU: 0657-0076) is a premium safety device engineered for heavy industrial oxy-fuel applications. As part of the Victor "Flamebuster" series, this unit is designed to provide a robust defense against two of the most dangerous occurrences in oxy-fuel cutting and welding: reverse flow of gases and flashbacks. The device is specifically configured for Oxygen service and features a "B" size (9/16"-18 RH) connection, making it compatible with the vast majority of industrial torch handles in North America.
Technically, the FBHC-O integrates two distinct safety mechanisms within a single brass housing. First, a reverse flow check valve utilizes a spring-loaded mechanism to prevent the accidental mixing of gases in the hose or regulator, which is a primary precursor to explosions. Second, a sintered stainless steel flame barrier acts as a flashback arrestor, effectively quenching any flame front that attempts to travel back from the torch tip into the gas supply line. This dual-redundancy is critical for maintaining a safe working environment.
A distinguishing feature of the FBHC-O model is its "High Flow" designation. Unlike standard arrestors that may restrict gas volume and starve large heating nozzles or cutting tips, the FBHC-O is engineered to pass sufficient gas volume for heavy-duty applications, such as structural steel fabrication and thick plate cutting. It is rated for use with Victor Heavy Industry torches and ensures that performance is not sacrificed for safety. The unit mounts directly to the torch inlet, placing the safety barrier as close to the potential hazard as possible.
