The HYSF MCBH4M is a robust 4-pin male bulkhead watertight connector ideal for panel-mount applications in harsh marine environments. Widely used in pressure housings, subsea junction boxes, ROV control systems, underwater lighting, and deep-sea instruments requiring secure through-bulkhead connections. Manufactured with 316L stainless steel or titanium options, gold-plated contacts, and neoprene overmolding, it achieves full ocean depth rating of 6000 meters (60 MPa) with IP68 sealing. High insulation resistance, low contact resistance, and exceptional durability ensure long-term reliability in offshore oil & gas and subsea projects.
