The single-core high-current waterproof connector is a rubber-body mateable pair built around one large gold-plated contact. It is the simple answer for a single power feed — battery charge lines, thruster supply, or a high-current lamp — through a sealed bulkhead, where a multi-pin connector would be wasted cost.
Product Highlights
- One big contact, one job: a single gold-plated high-current contact sized for power feed circuits rather than signals.
- Rubber-body construction: molded insulating body with integral seal geometry — the seal is part of the body, not an added gasket.
- Metal threaded base: brass / stainless threaded base seats into the housing with a compressed sealing shoulder.
- Mated pair from one source: plug and receptacle are supplied as a matched pair so contact geometry and retention are guaranteed.

Structure & Sealing
The receptacle rubber body compresses against the housing wall as the threaded metal base is tightened, sealing the penetration without a separate gasket. The plug inserts axially into the rubber socket — the interference fit both centers the contact and completes the seal — and a ground / pilot pin aligns the pair during mating.
Applications
- Battery charge pass-throughs on AUV / ROV hulls
- Thruster and propulsion power feeds
- High-current underwater lamp supply
- Subsea power distribution boxes
Customization & OEM
- Larger contact cross-sections for higher current
- Multi-core versions of the same rubber-body style
- Custom pigtail gauge and length
- Housing thread to drawing
Packaging & Delivery
Each connector is shipped in an ESD-safe bag with a protective cap on the mating face, packed in a foam-lined carton. Lead time depends on configuration and quantity — contact us for a current schedule. DHL / FedEx / air / sea freight supported.
FAQ
What current can this contact carry?
It depends on the contact cross-section and wire gauge you choose — send us the load and we will confirm the suitable size.
Is the pair keyed against wrong insertion?
Yes, the ground / pilot contact position keys the mating orientation.
Can I order receptacle only?
Yes, plug and receptacle are available separately or as a set.
Does the rubber body resist seawater long-term?
The body material is selected for marine immersion service; material data is available on request.
