Purpose and Body Fitment

The seal is designed for installation on the front right door, ensuring proper adhesion to the frame and window in this part of the body. The placement on the vehicle is clearly defined, minimizing the risk of error when selecting the part for a specific side of the car.

The black color of the seal is consistent with the standard finish of most equipment versions, allowing for a cohesive look of the door edges and the pillar. This element is particularly important when replacing a worn or leaky seal, where air leaks, wind noise at higher speeds, or water ingress into the interior occur.

Technical and Functional Characteristics

The door seal performs several key operational functions:

• limits the penetration of water and moisture into the cabin,
• reduces wind noise and external noise,
• helps maintain a stable temperature inside the vehicle,
• protects the door edges from direct contact with the body frame.

The part belongs to the Door Seals group, meaning it is designed to operate in variable weather conditions and with frequent opening and closing of doors. The seal's construction is adapted to the geometry of the front passenger-side door, facilitating installation and ensuring stable seating in the factory mounting points.

Item Condition and Service Application

The offered seal is a used part, making it an attractive solution for service repairs where a favorable cost-to-functionality ratio is a priority. This type of part is suitable for both replacing a damaged seal after a collision and for gradual wear and tear, manifesting as leaks or reduced acoustic comfort.

Selecting the correct seal for a specific model and body version is crucial for maintaining cabin tightness. In this case, the product is dedicated to the C W204 series, allowing for the preservation of factory door-to-body fitment parameters.

Benefits of Using a Dedicated Door Seal

Using a properly selected seal on the front right door brings tangible operational benefits:

• Improved driving comfort – reduction of wind noise and external noise.
• Better interior protection – reduced risk of damp upholstery and sill elements.
• Stable door closing – the proper elasticity of the seal supports the correct adhesion of the door leaf to the body.
• Aesthetic finish – the black color blends well with factory trim and surrounds.

Replacing a worn seal with a fitted part restores the door's original protective and acoustic properties, which is particularly important in cars used daily in varied weather conditions.
