Pollak 12-400 4-Way Flat Connector Dust Boot & Protective Cap – Weatherproof Cover

Protect Your Electrical Connections from the Elements The Pollak 12-400 is a heavy-duty protective dust boot designed specifically for 4-way flat trailer connectors. In the world of towing, the most common cause of lighting failure is corrosion at the plug. This simple yet effective cap acts as a primary line of defense, shielding your connector terminals from road salt, grime, moisture, and debris when your trailer is not in use.

Durable and Secure Fit Manufactured from high-quality, flexible rubber-like PVC, the Pollak 12-400 is built to withstand extreme temperatures without cracking or hardening. The cap features an integrated tether loop, allowing you to secure it directly to your wiring harness so it’s always right where you need it—no more lost caps at the boat ramp or job site.

Key Features:

• Universal 4-Way Compatibility: Designed to fit standard 4-pole flat connectors found on most light-duty trailers and vehicles.

• Corrosion Prevention: Keeps terminal pins clean and dry to ensure reliable electrical contact for turn signals, brake lights, and tail lights.

• Integrated Attachment Loop: Built-in strap secures the boot to the wire harness to prevent loss.

• Flexible PVC Construction: Engineered for long-lasting durability against UV rays and harsh road chemicals.
