What is the car front door sealing gasket?
The car front door seal plug generally refers to the car door seal strip, which is the black rubber strip around the edge of the front door frame.
Its main function is to seal, filling the gap between the car door and the body. It mainly does the following things:
• Waterproof and dust-proof: It can block rainwater when it rains or during car washing, and also prevent dust from entering, avoiding rust on the metal inside the car door and moisture on the electrical circuits.
• Sound insulation and noise reduction: It reduces wind noise and external noise from entering the car, making the interior quieter.
• Buffer and shock absorption: When closing the door, it uses the elasticity of the rubber to buffer the impact, reducing abnormal noise and also reducing the wear on the door hinges and locks.
Daily maintenance tips:
When washing the car, wipe the surface of the seal strip with a damp cloth to remove dirt, which can delay aging.
If you find it cracked, deformed or fallen off, it is recommended to replace it in time, otherwise the sealing and sound insulation effects will decrease.
Don't try to peel it off out of curiosity. If you remove it, the sealing of the car door will deteriorate, and there is a risk of abnormal noise when closing.
The car front door seal plug (also called the car door rubber plug) mainly seals, waterproofs, dust-proofs, and sounds-proofs. It can also prevent the metal from directly colliding when closing the door, causing the door to deform.
It can block the reserved process holes on the car door to prevent rain, dust, and wind noise from entering the car.
Without it, when closing the door, the metal parts collide directly, and over time, the car door is prone to deformation, cracks, and increased noise, and it can also affect the air conditioning effect.
This rubber plug is part of the original factory design. It is recommended not to remove it. If it is aging or falling off, replace it promptly. Original factory parts or brand-name parts are more durable.
In short: Don't think it's small; without it, the car door is prone to water leakage, dust entry, and abnormal noise.
If the car door seal plug (black rubber plug) is broken, the main impact is a decrease in sealing, easy dust entry, increased wind noise. As long as it is not severely damaged, most cases can be solved by yourself, and it costs only a few dozen yuan.
First, determine if it can be repaired:
• Only cracked or minor damage: Use the seal plug-specific adhesive to repair it. After cleaning the damaged area, apply the adhesive and press it firmly.
• Rubber aging, hardening, severe fracture or falling off: The repair effect is poor. It is recommended to replace it directly. Original factory parts or brand-name parts are more durable.
Replacement steps (do it yourself):
• Prepare tools: New seal plug, screwdriver, plastic pry bar (avoid scratching the car paint), cleaner, and dry cloth.
• Remove the old part: First, carefully remove the old seal plug using a screwdriver or pry bar. Be careful not to use a metal tool to pry, as it may damage the car door paint. If there is residual glue on the door frame, clean it up and dry it.
• Install the new part: Align the new seal plug with the original position and press it in place to ensure a tight fit. After installation, open and close the car door several times to check for looseness or air leakage.
When installing, be careful not to block the drainage holes at the bottom of the car door. Otherwise, during rainy days, it is easy to cause water accumulation in the car.
If you don't want to do it yourself:
Go to a 4S store or a reliable repair shop to replace it. The cost is not high. The labor cost plus the material cost is generally from several tens to two or three hundred yuan, depending on the model. If you are unsure whether you can do it yourself, it is safer to find a professional technician.
How to maintain it regularly:
Use car detergent to clean the area of the seal plug regularly. After cleaning, apply a layer of high-penetration protective agent to delay rubber aging.
Use a soft brush to clean the sand and dust in the gaps to avoid wearing the rubber.
