WESFA-10 - Western Enterprises FA-10 Torch Mount Flashback Arrestor Set

Comprehensive Safety for Oxy-Fuel Operations

The Western Enterprises FA-10 Flashback Arrestor Set is an essential safety component designed for professional oxy-fuel welding and cutting applications. Engineered to mitigate the risks associated with gas instability, these arrestors are specifically designed to mount directly onto the torch handle. This placement is critical as it provides the first line of defense against dangerous flashbacks and backfires, preventing flames from traveling upstream into the hoses, regulators, and cylinders. By stopping the flame at the torch, the FA-10 set ensures that the most vulnerable components of your gas delivery system—the rubber hoses—remain protected from internal combustion.

Advanced Engineering and Construction

Manufactured in the United States, the FA-10 set features a robust brass construction that withstands the rigors of industrial environments. Inside each unit lies a sophisticated safety mechanism comprising two main elements: a reverse flow check valve and a sintered metal flame barrier. The check valve automatically closes if gas pressure reverses, preventing the accidental mixing of oxygen and fuel gases which is a primary cause of explosions. Simultaneously, the sintered stainless steel filter acts as a heat sink, effectively quenching any flame front that attempts to pass through the device. This dual-action protection is UL Listed, ensuring it meets stringent safety standards for industrial use.

High Performance and Compatibility

Despite their compact size, the Western Enterprises FA-10 arrestors are engineered for high-capacity performance. They are rated to support gas flows sufficient for cutting steel up to 10 inches thick, ensuring that safety does not come at the cost of productivity. The set includes two color-coded units: a green arrestor for oxygen (CGA-022) and a red arrestor for fuel gases (CGA-023), which includes acetylene, propane, and propylene. Both units utilize standard B-Size 9/16"-18 UNF threads, making them compatible with the vast majority of North American cutting torches and welding handles. Whether used in a laboratory, a heavy fabrication shop, or on a construction site, the FA-10 set provides reliable, maintenance-free protection for operators and equipment alike.
