Pollak 12-907 9-Way RV-Style Connector Socket – Vehicle-Side 9-Pole Heavy-Duty Nylon Socket

The Reliable Hub for Advanced Trailer Electrical Systems

The Pollak 12-907 9-Way Connector Socket is the professional choice for vehicle-side trailer wiring. While maintaining the same compact footprint as a standard 7-way RV socket, the 12-907 provides two additional circuits, making it indispensable for trailers that require specialized power for interior lighting, winches, battery chargers, or "reefer" (refrigerated) unit thermostats.

Precision Engineering for Maximum Conductivity Built with Pollak’s industry-leading floating pin technology, this socket features self-aligning, solid round brass terminals. This design ensures a continuous "wiping action" during connection, removing oxidation and providing the most positive contact possible. By minimizing voltage drop, the 12-907 ensures your brakes and high-draw auxiliary accessories perform at peak efficiency.

Rugged, Weather-Resistant Construction Designed to endure the harshest trucking environments, the 12-907 is housed in high-impact, glass-filled black nylon. It features a heavy-duty stainless steel spring-loaded lid with a high-performance gasket that seals out dust, moisture, and road salt when not in use.

Key Features:

• 9-Pole High-Capacity Design: Offers expanded functionality for specialized auxiliary circuits.

• Floating Brass Pins: Self-aligning pins ensure easy mating and a secure electrical bond.

• Corrosion Protection: Solid brass terminals resist rust and oxidation for long-term reliability.

• Industry Standard Footprint: Fits into the same mounting holes as standard 7-way RV sockets (use bracket 12-711U or 12-701).

• Field Serviceable: Easy to access and repair, reducing downtime for fleet maintenance.

• Multi-Gauge Compatibility: Designed to accept a mix of 8-gauge, 12-gauge, and 14-gauge wires.

Common Applications:

• Specialized Horse & Livestock Trailers

• Refrigerated (Reefer) Trailers

• Custom RV & Overlanding Vehicle Builds

• Commercial Utility Trailers with multiple auxiliary functions
