This modular watertight enclosure is perfect for use on ROVs, AUVs, marine vehicles, and other harsh environments. This enclosure is part of the 4″ Series and has a 4″ inner diameter. A variety of options ensures the right enclosure for your needs. These pressure vessel enclosures are commonly used in a wide range of applications including MATE and Robosub ROVs, subsea batteries, cameras, electronics, data loggers, environmental monitoring, instrument housings, junction boxes, and more. This size is also the used as the main enclosure on the BlueROV2 and is ideal for use in many ROV and AUV projects.
When used with the clear acrylic plastic tube option, it’s easy to see the components inside the enclosure, ideal for subsea development projects and research ROVs and AUVs. The aluminum tube option provides a greater depth rating, opaque appearance, and better thermal transfer for high power applications like power supply housings and battery housings.
A variety of end caps are available for the ends of the enclosure including an optically clear acrylic dome, optically clear flat end cap, and aluminum end caps with 0, 5, 10, 14, and 18 holes, making it easy to attach any of our products with M10 threads like cable penetrators and pressure sensors. We also provide the 2d and 3d files for the end caps, allowing you to design and create custom end caps out of flat material to produce fully customized enclosures for any application.
