HYSF SFLPDC4F is a low-profile flat 4-pin female dummy plug with PU body. IP68 rated, 60 MPa tested, designed for protecting unused male 4-pin flat ports on Gigabit Ethernet systems, micro-ROVs, AUV flat panels, PTZ cameras and thin pressure housings up to 6000 m.
The HYSF SFLPDC4F is a dedicated female dummy plug that reliably seals exposed male 4-pin flat bulkhead connectors from seawater intrusion, biofouling and mechanical damage. Its streamlined black polyurethane body slides over SFLPBH4M ports, creating a complete pressure-tight mechanical barrier with no electrical connection.
Injection-molded from high-durometer UV-stabilized PU with integrated stainless steel retention clip and tether loop. Triple internal O-rings ensure secure locking onto the host connector shoulder while the large grip enables easy hand-installation even with thick gloves.
Essential for maintaining system integrity on high-speed Gigabit Ethernet flat-panel systems, deep-rated camera arrays and complex payloads when ports are temporarily unmated. ISO9001-2015 certified with 100 MPa burst rating and 500-hour UV resistance.
