When it comes to ensuring the longevity and performance of a vehicle, many components play an integral role, but one often overlooked feature is the water seal in car doors. The water seal, also known as a weatherstrip or door seal, is a rubber or foam strip that runs around the perimeter of a car door. Its primary function is to prevent water, dust, and noise from entering the vehicle, thus enhancing the driving experience and safeguarding the car’s interior.
Foam weather seals are typically made from materials such as polyurethane or polyethylene. They come in various shapes and sizes, allowing them to fit snugly into corners, gaps, and seams where air might escape or enter. Common applications include windows, doors, and other areas prone to drafts. The primary function of these seals is to create a barrier that blocks unwanted air movement, which can lead to significant energy loss.
