What is the rubber strip on the car door frame called?

[Juniper]

The rubber strip on the car door frame is called the door sealing strip. It is a product that seals the car door, making it harder to open, and serves functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Extended information: Functions: Mainly applied to door panels, door frames, side windows, front and rear windshields, engine hoods, and trunk lids, serving purposes in waterproofing, dust prevention, sound insulation, temperature insulation, shock absorption, and decoration. Composition: The door sealing system mainly targets two areas. One is the sealing of the door opening area, which relies primarily on an inner door sealing strip installed around the flanged edge of the side door opening or an outer door sealing strip installed around the door to seal the entire door opening. Some car models have both sealing strips, while others only have one. Different car models choose the sealing strategy based on performance requirements or cost objectives.

The rubber strip on the door frame is commonly called the door seal, also known as the dust strip or waterproof seal. From my years of driving experience, this little thing shouldn’t be underestimated. It acts as a sealing barrier, preventing rainwater, dust, or bugs from getting inside, while also significantly reducing wind and road noise at high speeds. Once it ages—becoming stiff, cracked, or deformed—it can lead to air leaks and water seepage inside the car. Especially during rainy seasons, a wet carpet isn’t just uncomfortable but can also cause mold or rust. I recommend checking it every six months. If you notice it’s no longer sealing properly, buy a new one from an auto parts store—EPDM rubber material is the most durable. Replacing it is simple: clean the old seal groove, apply some special adhesive, and snap it into place. Don’t wait until the problem worsens, or you’ll end up with loud wind noise and ineffective heating from the AC.

The rubber strip on the car door frame is commonly referred to as the door seal. As an automotive enthusiast, I've noticed during modifications that it significantly impacts the overall comfort of the vehicle. This seal is primarily made of rubber or silicone, designed to fit snugly between the door frame and body gap, effectively blocking wind and rain. If damaged, it not only causes excessive noise at high speeds but also allows rainwater to seep into electrical components, potentially causing short circuits. I usually clean it with specialized cleaners, avoiding harsh chemical products to prevent corrosion. If signs of aging are evident, I recommend replacing it with genuine parts at authorized shops, typically costing around 100 yuan, which is quite affordable. Regular maintenance can save you a lot of trouble, and replacing it with a new one immediately restores quietness and comfort, especially noticeable during long-distance trips.

That rubber strip is called the door seal, simply put, it's the thing that blocks the door gap. As a beginner who just started learning to drive, I didn't pay attention to it at first, and as a result, rainwater leaked into the car on rainy days, making the floor all wet. Now I know its role is to waterproof and keep out dust, plus it makes the car quieter when driving. A common issue is that it tends to crack or fall off after aging. If it feels hard or has cracks when touched, it's time to replace it. You can buy a new strip at an auto repair shop or online and install it yourself—super easy. Never overlook small details, or your car will be noisy and dirty.

The rubber strip on the door frame is professionally called the door seal, primarily used for sealing gaps. In routine maintenance, we often see materials like EPDM rubber, which offers good heat and weather resistance. Common issues include deformation, wear, or adhesive failure. During inspection, press it by hand; if it's loose or has a large gap, it should be addressed. Replacing it yourself isn't difficult: clean off the old adhesive residue, apply new adhesive, and align it into the groove. Otherwise, air leaks can increase fuel consumption, and water leakage during rain may damage the interior or electronic components. Regular maintenance, such as spraying silicone oil protectant, can extend its lifespan—low cost with good results.
