Apeks XL4 OCEA Stage 3 Regulator Set Grey

The XL4 OCEA combines a compact regulator layout with an over-balanced, dry-sealed first stage. Biobased and recycled second-stage polymers are used in the housing, while the small second stage and straightforward Venturi control keep the setup practical for travel and regular diving.

Features and benefits

Balanced gas delivery. The over-balanced diaphragm mechanism helps manage the supply to the second stage as diving conditions change.
Venturi control. Select the appropriate setting for surface handling or diving to help manage free-flow tendency.
Environmental protection. The sealed first-stage chamber helps keep water and contaminants away from its working mechanism.
Comfortable mouthpiece hold. The Comfo-Bite palate bridge helps support the second stage without a hard bite.

Setup and compatibility

Connection: DIN, Yoke. Choose the fitting that matches your cylinder valve and its pressure rating. Use the OCEA within its gas-compatibility limits; material or cleaning claims do not make the standard model a dedicated pure-oxygen regulator.

This Stage 3 listing includes the primary regulator and the matching listed octopus. Confirm the selected cylinder connection and any separately listed accessories before ordering.

The ergonomic Venturi lever is easy to use and locate.
