What is the rubber strip on the car door called?
2 Answers
The rubber strip on the car door is called the door seal. It is a product that seals the door, making it harder to open, and serves functions such as shock absorption, waterproofing, sound insulation, heat insulation, dustproofing, and fixing. It is mainly applied to the door frame, side windows, front and rear windshields, engine hood, and trunk lid, providing waterproofing, dustproofing, sound insulation, temperature insulation, shock absorption, and decoration. More details are as follows: The door sealing system mainly targets two areas: 1. Door opening area: It primarily relies on an inner door seal strip installed around the side panel door opening flange or an outer door seal strip installed around the door to seal the entire door opening. Some models have both seal strips, while others use only one, depending on performance requirements or cost targets. 2. Window area: This mainly relies on the glass guide channel seal strip on the window frame and the inner and outer window sill seal strips to achieve sealing. They also ensure the smooth up-and-down movement of the window glass. Typically, the glass guide channel seal strip has the highest requirements and the most complex structure in the vehicle sealing system.
Oh, when it comes to that rubber strip on the car door, people usually call it the door seal or simply the sealing strip. I think it's particularly important in daily driving—it prevents rainwater from seeping into the car and protects the door interior from rust and corrosion. I remember once when the seal on my car cracked due to aging, water dripped onto the floor mats during heavy rain, and the car smelled musty. After replacing it with a new one, everything was much cleaner. These seals are mostly made of rubber, which tends to harden and become brittle under sunlight, especially in older cars. I make it a habit to check them regularly, cleaning them with a damp cloth to remove dust and occasionally applying rubber conditioner to maintain elasticity. If you notice any deformation or peeling, replace it immediately to avoid bigger issues like corrosion of electronic components. Though small, this part is crucial for sound insulation and keeping the cabin dry. Replacing it yourself isn’t hard—just order one online for a few bucks, but make sure to get the right size for your car model.
