A subsea connector system is used to connect internally mounted couplers to provide sealed conduits for subsea operations. The system has a removable (outboard) connector and a fixed (inboard) connector each with a housing having special geometric properties that facilitate alignment and connection of the couplers. The latching mechanism has a latch pin in the fixed connector and a latch sleeve in the removable connector for receiving and latching to the latch pin. The couplers (male and female) and the latching mechanism are located within the housings of the fixed and removable connectors to provide protection for the components from damage during storage, handling, transport and installation operations.
