How to Make a Flame Arrester

Back with a new video, it's about how to make a Flame Arrester. It is a completely homemade device, which allows gas to pass through it, but stops a flame to prevent a fire or explosion. The arrester allows the free flow of gas or steam through the piping system. If the mixture ignites and the flame begins to recede through the pipe, this device cuts off and prohibits the flame from returning to the gas source.
It is ideal for blowtorch, torch, regulator, acetylene.
