Uniweld rfab Flashback Arrestor Oxygen Fuel B Fitting

Product Description

The UNIWELD rfab is a flashback arrestor designed for use with oxygen and fuel gas welding and cutting systems, installed at the regulator with a B fitting connection. Flashback arrestors protect operators and equipment by stopping reverse flame travel and gas backflow through hoses and regulators. This model is rated for regulator-side installation, making it a critical safety component for any oxy-fuel torch setup. Licensed welding and cutting professionals rely on devices like the rfab to meet safety requirements and protect expensive torch equipment from damage caused by flashback events.

The rfab is suited for regulator-side installation on oxygen and fuel gas systems commonly found in welding shops, metal fabrication facilities, and field cutting operations. The B fitting connection type is a standard interface used across many oxy-fuel regulators and hose assemblies, making this arrestor a straightforward fit in a wide range of professional cutting and welding setups. It is appropriate for both shop use and portable oxy-fuel rigs used in field service.

Key Features

• Regulator-side mounting position for protection at the gas source
• Compatible with both oxygen and fuel gas systems

Compatibility

Designed for regulator-side installation on standard oxy-fuel cutting and welding systems using a B fitting connection.

Installation Notes

Installation should be performed by a qualified welder or gas systems technician familiar with oxy-fuel equipment. Shut off all gas supply at the cylinders and bleed hose pressure completely before installing or replacing a flashback arrestor. Hand-tighten the B fitting connection first, then snug with the appropriate wrench — do not overtighten fittings on gas equipment. After installation, perform a leak check using an approved leak-detection solution before re-igniting any torch.
