Waterproof Rubber Grommets

Waterproof Rubber Grommets are installed in body panel pass-through holes. They protect wire harnesses and tubes passing through metal holes from sharp edge damage. They also provide sealing against water, dust, and noise. A typical vehicle has dozens of wire and tube passages through body panels. Each passage needs a Waterproof Rubber Grommet to protect the harness and prevent water, air, and noise from entering the cabin through the hole. This grommet determines whether wires are "cut-free," whether the cabin is "watertight," and whether road noise is "blocked out." In simple terms, it keeps every wire "passing safely" and the body "sealed against wind and water."
