The rubber seals fitted around car doors and windows form a protective barrier. These seals prevent the ingress of water, air, and dust, ensuring a comfortable and quiet cabin environment. They also contribute to the vehicle’s structural integrity by helping to secure the doors and windows firmly in place. A typical example includes the seal around the door frame itself, as well as seals around the windows within the door.
Effective sealing plays a vital role in maintaining a vehicle’s internal climate, reducing noise levels, and protecting against corrosion. Without these seals, passengers would experience drafts, water leaks, and excessive road noise. Historically, simpler materials like felt were used, but modern vehicles benefit from advanced rubber compounds designed for durability and resistance to temperature extremes and UV degradation. This evolution reflects the increasing demands for passenger comfort and vehicle longevity.
