Victor FB-OR Oxygen Regulator Flashback Arrestor with Check Valve

Victor 0657-0014 FB-OR Heavy Duty Oxygen Flashback Arrestor

The Victor Flamebuster Plus FB-OR (0657-0014) represents the gold standard in oxy-fuel gas safety equipment. Designed for professional welders and fabricators who demand reliability without compromising performance, this regulator-mount flashback arrestor is engineered to handle the rigorous demands of heavy industry. When working with high-pressure oxygen systems, ensuring that flames and reverse gas flow are stopped before they reach the cylinder is critical. The FB-OR delivers this protection in a robust, high-flow package.

Technical Superiority and Flow Performance

Unlike standard light-duty arrestors that can restrict flow and cause torch starvation, the Victor FB-OR is built for High Flow Capacity. This is essential when running large multi-flame heating heads or cutting thick steel sections where oxygen demand is substantial. The internal geometry is optimized to minimize pressure drop while maintaining the highest safety standards. This ensures that your torch performs at its peak potential while maintaining full compliance with safety regulations.

Construction and Specifications

Built to last, the FB-OR features a durable brass housing that resists corrosion and withstands the physical abuse of industrial environments. The unit integrates a sintered metal flame barrier and a reverse flow check valve into a compact assembly.

Why Choose Regulator Mount?

Mounting arrestors at the regulator offers specific advantages. It protects the regulator and the cylinder—the most energetic parts of the system—from fire and explosion. While torch-mount arrestors protect the hose, regulator-mount units like the FB-OR provide the ultimate backstop for the gas supply. Victor recommends the use of these devices whenever possible to create a redundant safety protocol. The FB-OR's "B" size fittings ensure it mates perfectly with standard industrial hoses and regulators, allowing for a quick, leak-free installation using standard wrenches.

Equip your gas apparatus with the Victor 0657-0014 to ensure compliance with safety standards and to protect your valuable assets from the hazards of flashbacks and reverse flow.
