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.
