Victor FB-FR Fuel Regulator Flashback Arrestor

Protect Your Shop with Victor Flamebuster Safety

Safety should never be an afterthought when working with oxy-fuel equipment. The Victor Flamebuster Plus FB-FR (0657-0015) is your first line of defense against catastrophic equipment failure. Designed to screw directly onto your fuel gas regulator, this device stops flashbacks before they can reach your tank. If you are running a torch for cutting, heating, or welding, installing a high-quality flashback arrestor at the regulator is one of the smartest safety upgrades you can make.

This unit does double duty. First, it acts as a check valve, ensuring that oxygen cannot backfeed into your fuel line—a common cause of explosions. Second, if a flashback does happen (where the flame travels back up the hose), the internal arrestor snuffs out the fire instantly, protecting your regulator and cylinder. The "Regulator Mount" design is particularly effective because it protects the most critical part of your gas supply system. Unlike some restrictive safety devices that make your torch sputter, the Victor FB-FR is a "Heavy Duty" model, meaning it allows enough gas flow for big jobs, like heating thick steel or cutting heavy plate.

Installation is simple: just unscrew your fuel hose from the regulator, screw the Flamebuster FB-FR onto the regulator outlet (remember, it's a left-hand thread for fuel), and then attach your hose to the arrestor. It fits standard "B" size connections found on almost all professional welding gear. Whether you are a professional fabricator or a serious hobbyist, relying on Victor's proven technology gives you the peace of mind to focus on your weld, knowing your equipment is secure.
