Flashback Arrestor Set for Regulator Mounting

This Harris 88-5FBR-R set installs directly on the regulator for oxy-fuel systems. It provides flashback protection for both oxygen and fuel gas lines in a single package. The brass and stainless-steel body suits professional welding and cutting setups.

Sustained Operation With UL-Listed Protection

The arrestors meet UL-listed standards for continuous service under normal welding conditions. They stop reverse gas flow and flame propagation before either can reach the regulator or supply hose. Performance remains consistent during extended cutting or heating jobs.

Brass and Stainless Construction Handles Heat

The mixed-metal body resists corrosion and dissipates heat without external cooling. Standard 9/16 in.-18 UNF connections with CGA 022 oxygen and CGA 023 fuel inlets keep leak paths short. California Proposition 65 warnings apply to chemicals in the component materials.

Questions about this item

Does the 88-5FBR-R set generate noise, heat or draw power during continuous use?

The arrestor set is a passive brass and stainless-steel device with no moving parts, so it produces no noise, no heat and consumes no power while installed.

What regulator fittings must already be on my torch system for the 9/16 in.-18 UNF inlets to connect?

Your oxygen regulator needs a CGA 022 outlet and your fuel regulator a CGA 023 outlet, both with 9/16 in.-18 UNF threads, to mate with the arrestor inlets.

Will the B-size hose fittings on the outlets work with the older B-size hoses I already own?

Yes, the outlet connections are standard B-size hose fittings, so existing B-size oxygen and fuel hoses attach directly without adapters.
