Product Description
This export-grade flashback arrestor is specially designed to install on the outlet of oxygen or acetylene pressure regulators. It is made of full brass for outstanding high-temperature resistance, corrosion resistance and impact resistance, suitable for industrial workshops and construction sites.
Flashback is a major safety hazard during oxy-fuel gas cutting and welding. When flame reverses back along the hose, it may damage the regulator or even trigger cylinder explosion. This brass flashback arrestor adopts internal flame-quenching and pressure shut-off mechanism. Once flashback occurs, it instantly extinguishes flame and cuts off reverse gas flow to protect the gas cylinder and pressure reducer. It also works as one-way valve to avoid gas backflow under abnormal pressure.
Oxygen and acetylene models have different internal structures and threads. Oxygen adopts right-hand thread while acetylene uses left-hand thread, cannot be interchanged. The product has a marked gas flow arrow; installation must follow the flow direction. Simple screw mounting directly onto regulator outlet, no extra tools needed. Compact cylindrical design resists vibration and fits standard gas hose connections. Every unit passes strict safety inspection to meet international export standards.
This safety device is widely used in oxyacetylene welding, gas cutting, metal processing, pipeline installation, mechanical maintenance and shipyard work. It is essential PPE for welders and cutting operators. Many professional users install flashback arrestors both at regulator end and torch end for double safety protection
