Rubber grommets are flexible pieces, collared to keep them in place within a hole. The rubber ring creates a mechanical buffer between the metal and the other component. This prevents the component from rubbing against the metal and wearing through, causing shorts or leaks and creating malfunctions. The grommets are also able to prevent the grounding of electrical wire when it is passing through metal components.
