Oxygen Gas Flashback Device — complete protection assemblies for oxygen gas lines
An Oxygen Gas Flashback Device from REAL GAZ may be a single arrestor, a combined arrestor-and-valve unit or a full protection assembly mounted at the cylinder, manifold or torch. We help you choose the format that fits your equipment and risk assessment.
Every device is intended for oxygen only and is marked accordingly to prevent use on fuel gases.
Every device is intended for oxygen only and is marked accordingly to prevent use on fuel gases.
Where applicable devices follow EN ISO 5175-1, and fuel-gas pairing is considered against ISO 15615 for acetylene equipment, suitable for multi-gas workshops and plant installations.
Because a flashback device can be fitted in different positions, the choice depends on the risk assessment. A device at the cylinder regulator protects the cylinder and regulator; one at the torch protects the hose; a pipeline unit protects the whole branch. In high-risk settings, devices at several positions provide layered protection. We can explain the advantages of each position and suggest combinations for your equipment. Typical working pressures for oxygen devices range from 2.5 to 10 bar in the outlet line, and inlet ratings reach cylinder pressure on regulator-mounted versions. Please state the highest pressure that can occur, including faults.
