Pollak 12-725 6-Way Round Pin Plug to 7-Way RV Blade Socket Adapter Harness

The Pollak 12-725 is the professional-grade solution for vehicle owners with a standard 6-pole round pin socket who need to tow trailers equipped with a 7-pole RV-style blade plug. This heavy-duty harness adapter eliminates the need for permanent rewiring, allowing you to switch between utility trailers and modern campers or horse trailers with ease.

Constructed with a non-corrosive, glass-filled nylon shell, this adapter is built to survive the toughest environments. Unlike standard plastic adapters, the Pollak 12-725 resists impact, moisture, and road chemicals. The internal wiring is protected by a durable split-loom conduit, ensuring that your electrical signals stay shielded from abrasion and debris.

The 7-way RV blade socket features a high-tension spring-loaded lid that keeps the connection secure while driving and seals out dust and water when not in use. On the vehicle side, the 6-way round plug provides a positive, latching fit for consistent electrical contact across all circuits.

• Plug-and-Play Conversion: Instantly adapts a vehicle’s 6-Way Round socket to a 7-Way RV Blade trailer connection.

• Heavy-Duty Materials: High-impact, glass-filled nylon housing prevents rust and corrosion.
