Flashback Arrestor

A flashback arrestor is a safety device used in oxy-fuel welding, cutting, brazing, and heating systems to stop flames from travelling backward through the hose toward the regulator or gas cylinder. It helps protect operators, equipment and gas systems from flashbacks, reverse gas flow, and pressure-related hazards.

A cylinder flashback arrestor is commonly installed near the regulator or cylinder outlet to provide an additional layer of protection. The correct flashback arrestor for cylinder use should match the gas type, connection size, pressure rating, and system requirements. Regular inspection, proper installation and timely replacement are important for reliable performance.
