The Large Cylindrical Underwater Sealed Compartment with Multi-Connector End Face is a sealed underwater enclosure rated for deep submersion: electronics, instruments or energy storage sit inside a machined marine-grade alloy (per drawing) housing closed by an O-ring end cap, with all cabling leaving through watertight penetrations. It gives your payload a dry, pressure-proof home on ROVs, AUVs, seafloor stations and offshore equipment.

Product Highlights
- On request depth rating: hollow-section walls and restrained end cap carry the external pressure.
- marine-grade alloy (per drawing) housing: machined, corrosion-resistant body for permanent subsea exposure.
- O-ring end cap: grooved, reusable seal for service access without re-machining.
- Watertight penetrations: wet-mate connectors or potted glands in machined ports.
- Payload-friendly: internal mounting points for boards, sensors and instruments.
- OEM/ODM: diameter, length, depth class and port layout built to your drawing.

Structure & Pressure Design
Walls are sized for the external pressure at rating depth with a safety margin on buckling, not just burst; stiffeners or increased wall sections are added where the length-to-diameter ratio demands it. Every penetration sits in a machined boss with a controlled seal land, and the finished vessel is pressure-tested before shipment.
Applications
- ROV/AUV electronics and instrument housings
- Seafloor observation and monitoring stations
- Offshore subsea engineering equipment enclosures
Customization & OEM
- Diameter, length and end-cap style per your drawing.
- Depth class and material (316L / titanium / alloy) sized to the working depth.
- Port layout: wet-mate connectors, potted glands and blind bosses as required.
- Internal rails, standoffs and battery restraints for your payload.

FAQ
What is the MOQ?
MOQ is 1 piece for trial orders; volume pricing is available on request.
Can you build to my drawing?
Yes — diameter, length, material, depth class and port layout are all made to order; send the drawing for a quote.
How is the depth rating verified?
Each vessel is pressure-tested before shipment; test depth and duration are reported with the unit.
Can penetrations be added later?
Ports can be machined in at order time; adding them after delivery is possible but requires re-proof testing.
Is there a warranty?
One year warranty with technical support; spare parts available on request.
How do you ship?
Foam-packed export case; express, air or sea freight per size.
