IP68 Deep Sea Stainless Steel High Current Underwater Waterproof Plug Connector

Description: IP68 Deep Sea Stainless Steel High Current Underwater Waterproof Plug Connector. IP68 watertight high-current connector for ROV thrusters, subsea battery packs and power distribution; gold-plated contacts, bulkhead and cable versions, MOQ 1 piece, OEM/ODM welcome.

The IP68 Deep Sea Stainless Steel High Current Underwater Waterproof Plug Connector is an IP68-rated high-current underwater connector for circuits that carry real power: thrusters, battery packs, high-output lights and winch drives. Thick-section gold-plated contacts and a sealed, corrosion-resistant body let it pass high current at low voltage drop without overheating in a wet housing.

Product Highlights

  • High-current contacts: oversized gold-plated pins and sockets keep voltage drop and self-heating low under continuous load.
  • IP68 sealing: O-ring face seal plus potted cable exit hold the dry side against seawater.
  • Stainless steel 316L housing: corrosion-resistant body for continuous immersion and salt-water service.
  • Heavy-gauge cable support: rear entry accepts large conductor sizes used on power feeds and thruster lines.
  • Plug, socket or mated set: supplied as cable plug, bulkhead receptacle or complete mated assembly.
  • OEM/ODM: pin count, cable gauge, shell material and marking built to your drawing.

Structure & Sealing

Power contacts sit in a molded insulator inside stainless steel 316l housing, spaced for the creepage distance a high-current circuit needs. Sealing is an O-ring face seal at the mating interface plus a potted cable exit at the rear; the threaded coupling nut clamps the pair under tension so the seal faces stay compressed while the cable is loaded.

FAQ

What current can it carry?
The rating depends on pin count and cable gauge — send your load profile and we will confirm the configuration.

Can you supply a mated set?
Yes — plug, receptacle, bulkhead and ready-terminated cable assemblies can be quoted together.

Can you build to my drawing?
Yes. Contact size, shell, cable and termination can be customized; send your drawing for a proposal.

What is the lead time?
It depends on stock and customization level — contact us with your configuration for a firm date.

How is the connector sealed?
An O-ring face seal plus a potted cable exit; each unit is pressure-checked before shipment.

How do you ship?
Express (DHL / FedEx / UPS / TNT) for small lots; air or sea freight for bulk orders.
