ESAB FR 18 Flashback Arrestor for Oxygen – 10 Bar Torch-Mounted Safety Arrestor

ESAB FR 18 Flashback Arrestor for Oxygen

The ESAB FR 18 Flashback Arrestor is a cylindrical, torch-mounted safety device designed to provide protection in oxygen gas welding and cutting systems. It incorporates a non-return valve and flame-arresting element to help prevent dangerous reverse gas flow and stop a flame from travelling through the gas supply.

The oxygen-specific FR 18 is listed by ESAB India under product number 4300100426 and has a maximum operating pressure of 10 bar. It is designed for connection at the torch end of compatible gas equipment. (esab.com)

Oxygen Flashback Protection

The ESAB FR 18 Flashback Arrestor is designed for use with oxygen. Flashbacks can occur in gas welding and cutting systems when combustion travels backward from the torch toward the gas supply.

The FR 18 provides an additional layer of safety by incorporating a flame-arresting element that helps quench the flame and a non-return valve that prevents gas from flowing in the opposite direction.

For oxygen systems, ESAB specifies a maximum operating pressure of 10 bar for the FR 18 oxygen model. (esab.com)

Non-Return Valve

A key component of the ESAB FR 18 Flashback Arrestor is its non-return valve.

The non-return valve is designed to prevent gas from passing in the direction opposite to normal flow. This helps reduce the possibility of oxygen and fuel gas moving incorrectly through the system.

ESAB identifies the non-return valve as one of the principal safety elements of its cylindrical flashback arrestor range. (esab.com)

Flame Arrestor

The integrated flame-arresting element is designed to stop a flame from travelling beyond the arrestor.

ESAB describes the cylindrical FR 18 design as using a large cylindrical flame-arresting element. The larger element provides a substantial surface area for arresting the flame while supporting the gas flow required during operation. (esab.com)

Torch-Mounted Design

The ESAB FR 18 Flashback Arrestor is designed to be connected to the torch end of a compatible gas-cutting or gas-welding system.

Torch-mounted protection places the arrestor close to the source of the flame, providing an important protective barrier between the torch and upstream gas equipment.

The exact connection arrangement must always be checked against the torch and gas equipment being used.

10 Bar Oxygen Service

The oxygen version of the ESAB FR 18 Flashback Arrestor is specified for a maximum operating pressure of 10 bar.

The product should never be operated above its specified pressure rating. Gas pressure must always be set according to the applicable torch, nozzle, regulator and manufacturer’s operating instructions.

3/8″ BSP RH Connections

The FR 18 oxygen model uses 3/8″ BSP RH connections according to current ESAB and Indian product information.

This connection specification is important when selecting the correct flashback arrestor for an existing torch or gas-cutting setup. Always verify the connection type before ordering.

Cylindrical High-Flow Design

The ESAB FR 18 Flashback Arrestor belongs to ESAB’s cylindrical flashback arrestor range. The cylindrical design uses a large flame-arresting element intended to provide effective flashback protection without unnecessarily restricting gas flow during normal operation.

This makes the FR 18 suitable for professional gas-cutting and welding equipment where both safety and appropriate gas flow are important.

Applications

The ESAB FR 18 oxygen flashback arrestor can be used in compatible:

• Gas cutting systems
• Gas welding systems
• Oxy-fuel cutting equipment
• Fabrication workshops

Why Choose ESAB FR 18 Flashback Arrestor?

The ESAB FR 18 Flashback Arrestor provides an important safety component for compatible oxygen gas systems. Its combination of a non-return valve and flame-arresting element is designed to help protect the upstream gas supply against reverse flow and flashback.

Its cylindrical construction and torch-mounted configuration make it suitable for professional gas-cutting and welding equipment. The 10-bar maximum operating pressure also provides compatibility with appropriately specified oxygen systems.

For industrial workshops, fabrication companies and professional gas-cutting operators, selecting the correct flashback arrestor for the gas service and connection type is essential.

Safety Information

A flashback arrestor is a safety device and should not be treated as a substitute for proper gas-system installation, maintenance and operating procedures.

Always verify gas type, pressure rating, connection type and installation position before use. Inspect the equipment regularly and replace damaged or malfunctioning safety components.

Use appropriate regulators, hoses, flashback protection and other safety equipment specified for the gas system. Follow ESAB’s installation and operating instructions and applicable workplace safety requirements.
