DC3F Subsea Dummy Connector — 3-Contact Female Protective Cap, Circular Series

DC3F Subsea Dummy Connector — Overview

The DC3F is a 3-contact Female dummy connector (protective cap) for the subsea circular connector series. It mates with any unmated 3-contact circular male connector — whether bulkhead or inline — to seal and protect the contact face during storage, transit, and deployment intervals when the working connector is not connected.

Constructed from the same chloroprene rubber and gold-plated contact materials as the working connectors, the DC3F maintains a rated seal pressure and protects contacts from biofouling, corrosion, and mechanical damage. It is an essential component for any subsea deployment program where connectors remain unmated for extended periods on the seabed or during surface handling.

Key Design Features

• Protective dummy cap for 3-contact female circular connectors — seals unmated connector faces against seawater ingress, biofouling, and mechanical impact
• Same chloroprene rubber construction as working connectors — rated to the same depth and temperature range, maintains seal integrity throughout long deployments
• Gold-plated contacts — preserves mating-face gold plating on the working connector by preventing galvanic contact with dissimilar metals during storage
• Keyed interface — aligns correctly to the working connector's keying pin, ensuring the dummy cannot be incorrectly installed
• Compatible with all 3-contact circular series bulkhead and inline connectors — universal protective solution across the entire 3-contact platform
• Rated beyond 500 mate/demate cycles — dummy connectors can be installed and removed repeatedly without degrading the working connector's contact face
• Essential for observatory and mooring programs — protects unused ports on junction boxes and instrument frames during unattended seabed deployments
• Available from 1 unit, standard 1–2 week lead time

Specifications

Typical Applications

• Protecting unmated 3-contact bulkhead connectors on ROV chassis during deck operations and transit
