It’s a three-piece assembly—a pre-tapped cap, threaded base, and a PVC grommet—that tightens around the cable to keep out moisture, dirt, and debris. By maintaining a clean, weatherproof connection point, it helps prevent corrosion and electrical issues in the trailer or truck harness. You replace it when the original fitting cracks, the grommet dries out and no longer seals, or you’re installing a new junction box and cabling.
