Rubber grommets are small, ring-shaped devices made from flexible rubber. They are used to protect wires, cables, or pipes that pass through holes in various materials, such as metal or plastic. By providing a cushioning barrier, grommets help prevent wear and tear, reducing the risk of damage to the items they encase. These grommets also serve to minimize vibrations and noise, making them useful in automotive and industrial applications. Available in various sizes and shapes, rubber grommets can be easily installed and are often used in electronics, machinery, and construction projects to ensure safety and durability.
