This high-quality flashback arrestor set is designed for use at the regulator end of oxygen–fuel gas systems. Built with 9/16″-18 B-size threads, it ensures reliable connection and superior safety.
The acetylene arrestor included in the set is also suitable for Propane and MAPP gas, offering flexibility for different applications. Installing flashback arrestors at the regulators is critical—without them, there is a possibility of a flame traveling back through the hose and reaching the cylinders, which can result in a hazardous explosion. With these safety devices in place, that risk is eliminated.
Check valves alone provide only basic protection, while flashback arrestors act as a second line of defense, ensuring maximum safety for cutting and welding operations.
