The XL4 Ocea presents a new concept of regulator to the diving market. One that comes with the inherent build quality and performance shared by all Apeks regulators, but having the prime objective of being the first totally sustainably produced regulator available. Every manufacturing detail has been considered and adjusted to ensure each material and process has been optimized in the pursuit of minimal environmental impact. Our partnership with PlasticBank, establishes the XL4 Ocea as the world's first ocean plastic negative regulator.

The Ocea is the first of its kind – an environmentally-conscious regulator made from recycled materials and bio-plastics, manufactured in a solar-powered facility. Based on the XL4+, every single material and process was reconsidered to create the most eco-sensitive scuba diving regulator in the world. The Ocea is a truly game-changing regulator that removes five times its own weight in plastic from the environment.

First Stage

• Compact machined first stage based on the expedition tested Apeks DS4 platform.
• Break through, innovative over-moulded first-stage endcap and environmental diaphragm helps prevent ice build-up that can cause first stage free flow in extreme circumstances.
• Large surface area heat exchanger diaphragm clamp helps increase the gas temperature inside the first stage, resulting in improved cold water performance.
• Unique over-balanced diaphragm design - as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth.
• 2 HP ports and 4MP ports
