Subsea Watertight Enclosure Box

This rugged aluminum enclosure is naturally UV-resistant, making it ideal for surface and shallow-water systems exposed to direct sunlight. As an engineered pressure vessel (PV), its corrosion-resistant construction supports a long operational lifespan, even during extended deployment in challenging underwater environments.

Integrated along the enclosure walls are twenty predrilled M10 through-holes, enabling seamless compatibility with Blu-Sub’s suite of M10 cable penetrators and a wide range of subsea components. These include vacuum plugs, subsea switches, potentiometers, signal indicators, displays, environmental sensors, and more—allowing reliable integration of complex electronics without the need for additional modification. The enclosure is designed to simplify the assembly of advanced subsea systems and underwater pressure housing configurations while ensuring durable watertight performance.
