The Durable Flange Connection Male Female Waterproof IP68 Connector for Subsea Rov and Underwater Thruster Applications 8 Pin Plug is an IP68-rated flange underwater connector: the mounting flange bolts the receptacle straight through a housing wall, so the seal is carried by the flange gasket instead of the threads — a rigid, torque-stable penetration for thruster pods, instrument housings and battery compartments. 8-pin gold-plated contacts pass power and signal through one sealed penetration, and the flange face keeps the joint watertight under vibration and cable pull.

Product Highlights
- Flange bulkhead mounting: bolts through the housing wall — the gasket carries the seal, not the threads, so the joint stays put under torque and vibration.
- IP68 sealing: flange face seal plus potted cable exit keep the dry side isolated from seawater.
- Machined flanged body with marine-grade plating: rigid machined construction for continuous immersion in salt water.
- Gold-plated contacts: stable contact resistance and corrosion resistance over long deployments.
- Plug, socket or mated pair: supplied as cable plug, flanged receptacle or ready-mated assembly.
- OEM/ODM: pin count, flange pattern, cable length and marking built to your drawing.

Structure & Sealing
Contacts are carried in a molded insulator inside the machined flanged body with marine-grade plating. The flange face is sealed with an O-ring or face gasket against the housing wall, and mounting screws clamp the joint to a controlled torque; the rear cable exit is potted so seawater cannot wick along the jacket. Because the seal plane is the flange face rather than a threaded gland, the joint resists loosening from propeller vibration and handling loads.
Applications
- Through-wall penetrations on ROV / AUV thruster pods and drive sections
- Instrument housings and battery compartments needing a rigid bolted seal
- Sonar heads, cameras and sensor housings
- Underwater robotics, marine research and monitoring equipment
Customization & OEM
- Pin count, contact type and flange pattern (bolt circle, hole count) built to order.
- Cable length, jacket material and pigtail terminations to your drawing.
- Shell material options: brass, stainless steel, PEEK polymer.
- Laser marking and custom packaging for OEM programs.
Packaging & Delivery
Each connector ships with a protective cap on the mating face, packed in a foam-lined export carton. Lead time depends on configuration and quantity — contact us for a current schedule. DHL / FedEx / air / sea freight supported.
FAQ
What is the MOQ?
MOQ is 1 piece for trial orders; volume pricing is available on request.
Why a flange mount instead of a threaded gland?
The flange gasket carries the seal, so the joint does not loosen under vibration and gives a repeatable, torque-controlled installation.
Can you match my housing bolt pattern?
Yes. Flange diameter, bolt circle and hole count can be made to your drawing.
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?
A flange 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.
