Hella Marine 3-Pole Waterproof Plug and Socket, Screw Terminals, IP67, Max 16A, Up to 48V

Overview

The Hella Marine 006803801 is a 3-pin waterproof plug and socket set with screw terminals for a clean, serviceable disconnect in boat wiring. It carries an IP67 rating, so once it is fully mated and tightened it is suited to wet areas that see spray, washdowns, and occasional temporary submersion.

It is a practical choice when you want to unplug a component for maintenance or storage without disturbing the rest of the harness, such as removable deck gear, accessories mounted on hatches, or wiring runs that need a regular break point. The plastic body also helps avoid the corrosion problems that show up around saltwater when metal connectors are left exposed.

Since this is a three-conductor connector, confirm your circuit needs three conductors and that your wire size will seat securely under the screw terminals. Plan for strain relief and a supported mounting position so the connection does not carry the load of a moving cable.

Key features

• 3-pin plug and matching socket for three-conductor circuits
• IP67-rated sealing when the connection is fully assembled
• Screw-terminal wiring for straightforward installation and future servicing
• Plastic housing for use in damp lockers, cockpits, and other exposed areas
• Creates a tidy disconnect point for equipment removal and troubleshooting
• Helps keep water out of the connection compared with open spade or bullet terminals

Installation and setup

Mount the socket where it will stay supported and protected from snagging, then route the cable so the plug does not hang by the conductors. Strip the wire cleanly, seat each conductor fully in the terminal, and tighten firmly. After the first outing, it is worth re-checking terminal tightness, especially on boats that see vibration.

For best long-term results in saltwater, use tinned marine wire and keep the connection clean during assembly so the seal can do its job. If the connector will be unplugged regularly, keep the protective cap in place when the socket is not in use to limit moisture and grime buildup.

Compatibility and fit

This connector is meant for low-voltage onboard wiring where you want a sealed, detachable connection. Make sure you have enough clearance for the plug and socket to mate in a straight line, and that the cable jacket can be clamped so any pulling force is taken by the strain relief, not the terminals.

Use cases on board

This is a good match for coastal and offshore boats that need a watertight disconnect between a fixed harness and a removable part of the boat. It is especially useful in places where a connection gets unplugged during seasonal storage, trailering, or routine access to equipment.

Maintenance and care

Rinse salt residue from the outside of the connector after heavy spray or washdowns, and avoid forcing the parts together if grit is present. Periodically inspect the sealing surfaces and cable entry for damage, and replace or re-terminate if the connection has been strained or shows signs of water ingress.
