Victor flashback arrestors are required between an __________________________ and the hose.

Victor flashback arrestors are essential safety devices used in gas welding and cutting processes. Their primary purpose is to prevent the backward flow of flames into the gas supply system, which can lead to dangerous situations such as explosions or fires.

The correct placement of these arrestors is crucial for safety. When considering the function of the arrestors, they are designed to be installed between the hose and the torch head. This setup allows them to stop any potential flashback from reaching the hoses and the gas supply, preventing hazards throughout the entire assembly.

In this context, the components connected by the hoses are important. The torch head is where the gases mix and combust to produce the flame needed for welding or cutting. Having the flashback arrestors positioned away from the torch head would not effectively mitigate the risk of flames traveling back through the hoses from the torch, which is why a component such as the inline pressure gauge or regulator, while they are important equipment in the gas delivery system, are not the correct answer here.

Thus, the most relevant connection for the flashback arrestors is indeed between the hoses and the torch head, emphasizing their role in protecting the user and equipment during thermite welding processes.
