HYSF RMG4M/F is a custom 4-pin underwater engineering cable plug from the RMG series. IP68-rated, 60 MPa tested, with robust overmolding for harsh marine environments, ideal for subsea power/signal transmission in ROVs, AUVs, and offshore engineering up to 6000m.





The HYSF RMG4M/F is a successfully customized **4-pin underwater engineering cable plug** from the rugged RMG series, designed for demanding offshore and subsea applications. Featuring **4 gold-plated high-current pins** in a **compact inline male configuration**, it ensures reliable power and signal delivery through heavy-duty engineering cables—perfect for ROV tether management, subsea pump interfaces, and AUV propulsion wiring.
Constructed with **marine-grade stainless steel coupling** and **durable PU overmolding** for superior abrasion and impact resistance, it includes **triple O-ring sealing** for IP68 waterproofing and pressure resistance to **60 MPa (8702 PSI / ~6000 m depth)**. The plug mates securely with standard RMG female receptacles, with optional locking sleeve for high-tension environments. Pre-assembled with color-coded flying leads for easy termination.
This engineering-focused plug was tailored for industrial subsea use where durability meets high-performance connectivity. HYSF offers full customization in pin rating, cable specs, overmold hardness, and environmental coatings. ISO9001-2015 certified and proven in offshore oil & gas operations.
