Automotive Rubber Grommet is an important rubber component used in automobiles and mechanical equipment, typically used to protect electrical wire grommets, pipes, or other equipment from punctures on metal or other material surfaces. The design of rubber nesting aims to provide isolation, waterproofing, and protection functions, while reducing pressure and friction to extend the service life of wires or pipelines. These nested structures are typically made of soft, wear-resistant rubber materials to ensure their ability to function under various environmental conditions, such as car engine cabins or other harsh conditions.
