OVERVIEW

Stay Safe with the Victor FB-O Oxygen Flashback Arrestor

Safety is the number one priority when working with oxy-fuel equipment, and the Victor 0657-0010 Flamebuster Plus (FB-O) is an essential addition to your torch setup. Flashbacks—where the flame travels back up into the torch or hoses—can be catastrophic, leading to equipment damage or serious injury. The FB-O is designed to stop these events in their tracks. By mounting directly to your torch handle, it acts as a guard right at the source, extinguishing flames instantly and preventing them from reaching your gas supply.

This unit isn't just a flashback arrestor; it also includes a built-in reverse flow check valve. This feature is vital because it stops gas from backing up into the wrong hose, which is often how dangerous gas mixtures form in the first place. If you are using a heavy-duty torch for thick cutting or heating, you need an arrestor that won't restrict your gas flow. The Victor FB-O is engineered for high-flow performance, ensuring that your flame remains stable and powerful even when using large tips. You won't have to sacrifice performance for safety.

Installation is straightforward. The FB-O screws directly onto the oxygen inlet of your torch handle (look for the "Oxygen" marking and right-hand threads). It fits standard B-size connections found on most Victor and compatible torches. Once installed, it adds minimal weight and bulk, allowing you to maneuver the torch comfortably. Whether you are a professional welder in a shipyard or a hobbyist in a garage, equipping your torch with a Victor Flamebuster is a smart investment in your personal safety and the longevity of your tools.

Why Choose the Victor FB-O?

  • Dual Protection: Stops both flashbacks and reverse gas flow.
  • High Performance: Won't starve your torch, even during heavy cutting.
  • Easy Fit: Standard threads make it compatible with most heavy-duty torches.
  • Peace of Mind: Genuine Victor quality ensures reliability when it matters most.

FAQ

A check valve only prevents the reverse flow of gas. A flashback arrestor prevents reverse flow AND contains a flame barrier to stop a flame from traveling past the device. The Victor FB-O contains both.

The FB-O is a 'Torch Mount' device. It screws directly onto the oxygen inlet of the torch handle, between the handle and the hose.

No. The FB-O (0657-0010) is designed specifically for Oxygen. It has Right-Hand threads (CGA 022) which will not fit fuel gas connections. You need the FB-F model for fuel gases.

The Victor Flamebuster Plus is a Heavy Duty model designed for high flow capacity. It is suitable for most heavy industrial applications, though extremely large heating tips may require specific high-flow checks.

Flashback arrestors should be tested annually by a qualified technician. If a flashback occurs, the unit should be inspected immediately. If flow is restricted or the check valve fails, it must be replaced.

This unit has standard 'B' size fittings, which are 9/16"-18 Right Hand threads, common on most industrial oxygen equipment.

Yes, as long as the torch handle uses standard B-size (9/16"-18) oxygen inlet threads, the Victor FB-O will fit.

Torch mount arrestors stop the flashback closer to the source (the tip), preventing the hose from becoming pressurized with an explosion. However, regulator mount arrestors protect the regulator and cylinder.
