Harris Oxygen Flashback Arrestor Regulator

The Harris 88-5FBHF-RR is a high-flow flashback arrestor designed for oxygen regulator mounting. It suits welding professionals and maintenance teams who require a safety device rated for oxygen service with standard UNF thread connections.

Brass and stainless steel body handles oxygen flow

The brass and stainless steel construction manages heat and pressure during normal oxygen cutting or welding operations. Connection sizes of 9/16 In. -18 on both inlet and outlet provide a secure fit without excessive torque or leakage risk.

CGA 022 and CGA 023 inlet compatibility

Supplied CGA 022 and CGA 023 inlet identifiers ensure correct gas-specific installation on oxygen and fuel lines. Hose fitting size B matches common torch hose assemblies, reducing the need for extra adapters during setup.

Questions about this item

How do I install the 9/16-18 UNF regulator fitting on an oxygen line, and what step is often missed?

Thread the 9/16-18 UNF inlet and outlet connections by hand, then tighten with a wrench; the step often missed is verifying the CGA 022 oxygen inlet matches the supply before pressurising.

What maintenance will the brass and stainless steel flashback arrestor need over time?

Inspect the internal check valve and filter element annually; replace the unit if flow drops or after any flashback event, as the arrestor is not field-serviceable.

What limit appears first during sustained high-flow oxygen use?

The 9/16-18 UNF connection and CGA 022 inlet set the maximum flow capacity; sustained demand beyond that rating will cause pressure drop across the arrestor body.
