DNC-2125 Underwater 3G-SDI M16 Long-Thread Rotatable Elbow Bulkhead Connector
DNC-2125 is an underwater 3G-SDI bulkhead connector with a rotatable 90-degree elbow design and M16x1 long-thread installation format.
This connector is designed to transmit 3G-SDI / HD-SDI video signal through underwater housings and marine enclosures while keeping the external cable routed horizontally along the housing instead of straight out from the port.
Overview
The DNC-2125 was developed for underwater video systems where cable direction matters. The rotatable elbow design allows the connector to be installed and positioned in the preferred direction on the housing, helping reduce cable stress and keeping the SDI cable closer to the housing body.
It is suitable for 1080p60 3G-SDI video workflows, broadcast-style underwater cameras, telemetry systems, high-speed cameras, inspection systems, and custom marine video equipment.

Why Use an Elbow SDI Bulkhead Connector?
A straight bulkhead connector can cause the external cable to extend vertically away from the housing. The DNC-2125 elbow design keeps the cable routed horizontally, which can reduce snagging, improve handling, and help protect the cable during underwater operation.
The rotatable design allows the installer to choose the preferred cable direction during setup, which is especially useful on compact housings, camera cages, ROV-style systems, and crowded underwater rigs.
Applications
- Underwater 3G-SDI camera systems
- HD-SDI live view and monitoring
- Broadcast-style underwater video systems
- High-speed camera housings
- Telemetry and inspection systems
- ROV-style marine video systems
- Custom underwater housings with 16mm ports
Water Block
The DNC-2125 underwater bulkhead connector comes with 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.

Frequently Asked Questions
What is DNC-2125 used for?
DNC-2125 is used to pass 3G-SDI / HD-SDI video signal through an underwater housing or marine enclosure using an M16 long-thread elbow bulkhead connection.
Why choose an elbow-style SDI connector?
The elbow design routes the cable horizontally along the housing, helping reduce cable stress, cable snagging, and impact risk compared with a straight connector.
Can the elbow direction be adjusted?
Yes. The connector has a rotatable elbow section, allowing the cable direction to be positioned during installation.
What cables are compatible?
Compatible Dive And See SDI cables include DNC-1062, DNC-1061, and DNC-1033.
What is the depth rating?
DNC-2125 is rated to 160m / 240 PSI.
