MCDC3M is a HYSF SUBSEA miniature 3-pin male dummy plug underwater connector designed to seal and protect unmated compatible connector interfaces in subsea systems. It provides a practical protection solution when a 3-pin underwater connection is not in use during storage, transport, maintenance, or equipment deployment.MCDC3M helps reduce exposure to contamination, seawater ingress, and corrosion at unused connector interfaces. HYSF SUBSEA lists a durable neoprene construction and a secure locking thread for this 3-pin subsea dummy plug. Its compact format is suitable for ROVs, AUVs, underwater instruments, sensor systems, subsea housings, and portable underwater equipment.MCDC3M belongs to the HYSF SUBSEA Micro Watertight Connector series, which is designed for compact, lightweight underwater connection systems and wet-mating applications. HYSF SUBSEA lists pressure resistance up to
6000 m (60 MPa) for MCDC3M. Confirm the exact mating interface, locking arrangement, operating depth, and project requirements with HYSF SUBSEA before ordering.

MCDC3M Subsea Connector Port Protection
MCDC3M provides dedicated 3-pin male protection for compatible HYSF SUBSEA Miniature Series connector systems. Use this underwater connector blanking plug when a subsea connector interface requires temporary protection before the final cable or mating connection is installed.
MCDC3M Applications
- ROV and AUV connector port protection
- Subsea sensor and instrumentation systems
- Underwater camera and lighting equipment
- Portable underwater equipment
- Subsea housings and test equipment
- Connector protection during storage, transportation, maintenance, and deployment
How to Select an MCDC3M Dummy Plug
Before ordering MCDC3M, confirm the exact connector interface that requires protection, the locking arrangement, the working depth, and the expected environmental conditions. Pin count alone does not confirm compatibility. HYSF SUBSEA can confirm the correct protection plug for the corresponding Miniature Series connector configuration.
