The Apeks XL4 Ocea Regulators Yucca with Flexi regulator hose 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 optimised in the pursuit of minimal environmental impact. Partnership with PlasticBank, establishes the Ocea as the world’s first ocean plastic negative regulator.

• Recycled polymers made from up to 70% post consumer waste (black components)
• Bioplastic plastic parts made from non petroleum based sources.
• Trivalent chrome plating uses less harmful chemicals and is kinder to the environment.
• Eco brass is lead free, easier to recycle and has a higher tensile strength than traditional brass.

Environmentally sealed first stage

An environmentally sealed dry chamber prevents water from coming into contact with the 1st stage spring to stop freezing.

Ocea first stages are over balanced which allows for maximum performance at depth. This results in superior performance at depth.

• Compact machined first stage based on the expedition tested Apeks DS4 platform.
• Lead free brass is kinder to the environment and reduces the regulators footprint.
• Trivalent chrome uses less energy than traditional chrome and is kinder to the environement.
• 2 HP ports and 4 MP ports.

XL4 Ocea is compact and lightweight

Compact and lightweight second stage improves comfort and helps reduce jaw fatigue on long duration dives. The Venturi lever disrupts the airflow inside the Ocea second stage to prevent accidental free flows at the surface.

Patented Apeks Comfobite mouthpiece reduces jaw fatigue and secures the second stage more comfortably. Comfobite mouthpiece has a unique bridge that fits across the upper palate and does not require bite pressure to stay in place. Re-useable mouthpiece clip makes it simple to change mouthpieces in the field.

• High performance pneumatically balanced lever operated poppet valve.
• Large, over moulded self-flushing and controllable purge button.
• Ergonomic Venturi lever is easy to use and locate.
• Flexible nylon braided hose has better cold water performance than a traditional rubber hose.
• Standard metallic hose connection for interchangeability.
• Re-useable mouthpiece clip makes it simple to change mouthpieces in the field.
• Durable and flexible rubber exhaust tee provides excellent bubble diversion.
