The Messer Flashback Arrestor for Regulator is a critical safety device used in oxy-fuel gas systems to protect both equipment and operators from hazards such as flashbacks, backfires, and reverse gas flow. Installed directly on the regulator, it ensures that flames or explosive mixtures cannot travel back into the gas supply line, preventing serious accidents.

Built with a robust flame arresting element and a non-return valve (check valve), it offers dual protection by instantly stopping reverse flow and extinguishing flashbacks. Designed for high flow capacity with minimal pressure drop, it guarantees smooth, uninterrupted gas supply during welding, cutting, and heating operations.

The Messer Flashback Arrestor Regulator DA+OX is a high-safety device designed for use with oxygen (OX) and fuel gases like acetylene (DA) in gas cutting, welding, heating, and allied operations. It protects both the operator and equipment by preventing dangerous flashbacks, backfires, and reverse gas flow from reaching the regulator and gas supply.

Constructed with robust materials, the arrestor features an integrated non-return valve (check valve) and a flame arresting element, ensuring maximum safety during high-pressure gas applications. It is compact, easy to install directly on regulators, and requires minimal maintenance.

Boris Flashback Arrestor

• Use: Safety device for gas welding/cutting. Prevents flashback (reverse flame or gas flow) from reaching cylinders, avoiding explosions/fire.

• Working: Has a non-return valve + flame arresting element (usually sintered metal). Stops backflow + quenches flame.

• Types: Inline (between torch & hose) or regulator-mounted (at cylinder outlet).

• Size: Compact (2–4 inches), standard gas fittings (BSP threads, oxygen/acetylene).
