Brief Description:

Introducing the DNC-2128, a straight-style bulkhead connector designed for Nauticam's NA-1DX-III housing, featuring a Mini HDMI connector. The M28x1 threaded design and low-profile right-angle HDMI connector make it ideal for compact underwater housings.

Water Block:

The underwater bulkhead connector comes with a built-in water block, serving a dual purpose. It helps maintain a vacuum inside your housing when using the AirLock Vacuum System and acts as a safeguard against water ingress due to potential issues with the external cable or the connection between the cable and the bulkhead connector.


Custom cable lengths and various connector types are available to meet your specific needs.


The straight-style bulkhead connector is compatible with Dive And See waterproof underwater HDMI cables and HDMI monitors. It works seamlessly with the 45-meter HDMI Fiber Optic cable DNC-1034.
