DNC-2119 Underwater Full-Size HDMI Bulkhead Connector for Aquatica A7SIII - 1 inch-14 Thread
DNC-2119 is an underwater full-size HDMI Type A bulkhead connector designed specifically for the Aquatica A7SIII underwater housing.
This connector uses a special 1 inch-14 thread and is intended for Aquatica A7SIII housing applications. It is not a standard Nauticam-style HDMI bulkhead connector and should be selected only when this thread and housing compatibility are required.
Overview
The DNC-2119 was developed to provide a high-quality underwater HDMI pass-through connection for Sony A7SIII systems inside Aquatica housings. It uses a low-profile 90-degree full-size HDMI connector to fit the tight internal space of the housing while allowing an external underwater HDMI cable to connect from outside.
This connector is designed for 1080p60 HDMI signal transmission and may support some 4K workflows depending on the complete HDMI cable, monitor, camera, and system configuration.
Important Compatibility Note
DNC-2119 has a special 1 inch-14 thread for Aquatica A7SIII housings.
It is not compatible with standard Nauticam or similar M16/M24 HDMI bulkhead connector ports. Please confirm housing thread and port compatibility before ordering.

Why This Connector Is Different
Most underwater HDMI bulkhead connectors use common M16 or M24 thread formats. DNC-2119 is different because it was made for a special 1 inch-14 threaded port used on Aquatica A7SIII housing applications.
The low-profile right-angle HDMI connector is useful when the internal housing space is limited and a straight HDMI plug would not fit cleanly.

Water Block
The DNC-2119 underwater HDMI bulkhead connector includes a built-in water block.
The water block helps keep vacuum inside the housing when using an AirLock vacuum system. It also helps protect the housing against water penetration if the external cable or external connector connection becomes damaged.
Applications
- Aquatica A7SIII underwater HDMI output
- Sony A7SIII underwater live view systems
- HDMI monitor connection from underwater housing
- Underwater video production and monitoring
- Pool, studio, inspection, and marine video workflows
- Custom HDMI pass-through systems requiring 1 inch-14 thread
Compatibility
DNC-2119 is compatible with Dive And See waterproof underwater HDMI cables and HDMI monitor systems when the housing thread and connector format match the application.
It works with the DNC-1034 45m HDMI fiber optic cable for compatible HDMI live video workflows.
