Think of a Dummy Plug as a “Helmet” for your connector.
- Protection: A dropped bulkhead without a dummy plug often results in bent pins, rendering the entire ROV unusable until replaced.
- Sealing: For bulkheads installed on an ROV, a pressure-rated Dummy Plug allows the vehicle to be submerged even if that specific port is not being used (e.g., diving without the sonar attached).
