How Often Should Car Door Seals Be Replaced?

[EmersonDella]

Car door seals should be replaced every 3 to 4 years. The functions of the seals are: noise reduction, waterproofing, and windproofing. The car door consists of the door body, door accessories, and interior trim panels. Its functions are: to provide access for the driver and passengers, isolate external disturbances, and to some extent, protect occupants from side impacts. The design requirements for car doors are: 1. Ensure convenient entry and exit for passengers, with an opening angle controlled at around 65 to 70 degrees; 2. During the opening process, there should be no interference with other parts; 3. The door should lock securely when closed and not open on its own while driving; 4. Have good sealing performance; 5. Have a large transparent area to meet lateral visibility requirements; 6. Have sufficient strength and rigidity to ensure reliable door operation, reduce door vibrations, improve vehicle side collision safety, and prevent door sagging.
