Designed for depth, the Oceanic ZEO FDX-I regulator with Maxflex Swivel Hose Set refines the EOS legacy for scuba diving gear. This Open Box unit is generally unused, may show minor blemishes, and original packaging may be missing; it does not carry a manufacturer warranty.

In scuba environments, the chrome-plated marine brass valve delivers corrosion resistance and enhanced cold-water performance. The all-metal valve housing promotes condensation from your exhalation, and when you inhale that moisture circulates with the airflow to help reduce dry mouth and improve long-term comfort.

Dynamic Adjustment technology, along with diver inhalation effort controls and a dive/pre-dive switch, give you precise airflow control at depth. The orthodontic mouthpiece, the Maxflex swivel hose, and the integrated design contribute to a comfortable fit for extended diving sessions. The ZEO second stage pairs with Oceanic’s FDX-I first stage, a cold-forged, over-balanced diaphragm regulator that is environmentally sealed. Its inline design minimizes pressure loss, delivering efficiency and a lighter gear setup.

Built for a wide range of diving environments—from tropical seas to colder-water sites—the ZEO/FDX-I combination provides dependable breathing performance, reliable operation, and compatibility with common scuba gear configurations.

Condition note: May be missing original packaging and minor blemishes (not noticeable after 1-2 dives). This product does not carry a valid manufacturer warranty.
