Underwater Miniature Circular Connector Dummy Plug for ROV

Description: Underwater Miniature Circular Connector Dummy Plug for ROV. IP68 watertight miniature connector for ROV, AUV and subsea equipment; MOQ 1 piece, OEM/ODM welcome.

The underwater miniature circular connector dummy plug for rov is a protective dummy plug for the miniature underwater circular series. It seals the mating face of a receptacle or cable connector when the line is not in use, keeping seawater and debris out of the contacts, and is fitted with the same threaded coupling nut interface as the live connectors.

Product Highlights

  • One sealed penetration: power and signal contacts cross the housing wall through a single O-ring sealed interface.
  • Machined stainless steel housing (316L on request): corrosion-resistant shell machined for seawater service.
  • Gold-plated contacts: low contact resistance and corrosion resistance over long subsea deployments.
  • IP68 sealing: O-ring face seal plus potted cable exit keep the dry side isolated from seawater.

Structure & Sealing

The dummy plug carries no contacts: its sealed face replicates the mating geometry of the live connectors, so fitting it to an open receptacle restores the IP68 barrier. A lanyard or captive retaining cap can be fitted to keep it with the line.
