Uniweld TFAB Torch Mount Flashback Arrestor Set

Product Description

The UNIWELD TFAB is a torch mount flashback arrestor set designed to protect welding and cutting operators from dangerous reverse flame travel in oxy-fuel torch systems. The set includes one oxygen-side arrestor and one fuel gas-side arrestor, each mounting directly at the torch body between the hose connections and torch inlets. Flashback arrestors are a critical safety component in any oxy-fuel setup, stopping a flashback flame before it can travel back through the hoses and regulators. These are installed by welding professionals, HVAC technicians, and pipefitters working with oxy-acetylene or oxy-fuel cutting and brazing equipment.

The TFAB set is suited for torch mount installation on standard oxy-fuel cutting, welding, and brazing torches used in residential and commercial trade applications. Typical uses include HVAC refrigerant line brazing, plumbing copper pipe work, and general metal fabrication. The torch mount position provides protection at the closest practical point to the flame source, which is the most effective location for flashback suppression.

Key Features

• Set includes one oxygen flashback arrestor and one fuel gas flashback arrestor
• Torch mount design installs directly at the torch inlet connections
• Stops reverse flame travel before it reaches hoses and regulators
• Appropriate for oxy-fuel cutting, welding, and brazing torch setups
• Sold as a matched pair for complete torch-end protection on both gas lines

Compatibility

Designed as a torch mount flashback arrestor set for use with standard oxy-fuel torch assemblies in cutting, welding, and brazing applications.

Installation Notes

Flashback arrestors must be installed by a qualified technician familiar with oxy-fuel system safety requirements. Before installation, shut off both oxygen and fuel gas supply valves at the cylinder and depressurize the hoses completely. Thread the oxygen arrestor onto the oxygen torch inlet and the fuel gas arrestor onto the fuel inlet, ensuring correct gas-side matching to avoid cross-connection. Follow all applicable safe practices outlined by the Compressed Gas Association and local code requirements when working with high-pressure gas systems.
