MCBH16M Titanium Alloy Double O-Ring Underwater Connector 16 Pin — RV POWER subsea electrical connector rated 300V DC/AC. Features Ti-6Al-4V titanium body, dual EPDM rubber O-ring seals for 600m depth. IP68 waterproof, corrosion-resistant, IEC 60529 certified. Ideal for ROV, AUV, oceanographic sensors, and marine robotics. Bulkhead mount, factory pre-wired. Bulk pricing available.
The MCBH16M is a premium underwater electrical connector engineered for demanding subsea applications. Featuring aerospace-grade Ti-6Al-4V titanium alloy housing and dual EPDM rubber O-ring sealing technology, this 16-pin connector delivers unmatched reliability in the harshest marine environments — from shallow coastal operations to full ocean depth missions.
While SubConn, Seacon, and Burton connectors rely on single-seal designs and standard brass housings, the RV POWER MCBH16M features dual O-ring sealing with independently pressurized chambers that provide redundant leak protection. If the outer seal is compromised during deep-water pressure cycles, the inner O-ring maintains complete subsea integrity — a critical safety feature for ROV tethers, AUV power buses, and oceanographic moorings that cannot afford unplanned recovery missions.
Our Ti-6Al-4V titanium body offers 3× the corrosion resistance of stainless steel in seawater environments, with a density of only 4.43 g/cm³ — 45% lighter than brass equivalents. This reduces connector assembly weight in subsea frames and vehicle harnesses without sacrificing structural integrity.
