Ford Focus Mk3 Door Seal Rubber Gasket Rear Left Right N/O/S BM51-A20782-BC

Ford Focus Mk3 Door Seal Rubber Gasket Rear Left Right is an original component from the Door seals group, designed for installation in the rear part of the vehicle body. Engineered specifically for this Ford model, it ensures a tight closure of the door panel, reduces noise, and provides stable door edge guidance during daily use.

Purpose and vehicle placement

The presented seal is intended for installation in the rear part of the vehicle body, on either the left or right side. This solution allows for the use of the same type of component on both sides of the vehicle, which simplifies part selection during bodywork maintenance and reduces the risk of errors when ordering. Thanks to its fitment to the specific geometry of the rear doors, the seal works evenly along the entire perimeter, which helps maintain proper pressure of the door panel against the body and improves acoustic comfort inside the cabin.

Technical and functional characteristics

The seal is made of flexible rubber with parameters selected for operation in variable weather conditions. The material maintains its elasticity at both low and high temperatures, which reduces the risk of leaks during frost and overheating during the summer season.

• stable door edge guidance during repeated opening and closing,
• prevention of water and contaminants from entering the interior,
• reduction of wind noise when driving at higher speeds,
• support for proper rear door closing. The properly selected rubber cross-section and working profile of the seal promote even pressure distribution along the entire length, which is important for long-term operation and maintaining stable sealing parameters.

Benefits of using an original Ford seal

Using a component dedicated to Ford allows for maintaining the factory fit between the door and the body. Original seal geometry minimizes the need for additional adjustments during installation and facilitates service work, especially when replacing after a collision or after long-term use. Choosing this seal also means:

• consistency with other Ford body components,
• easier diagnostics of potential leaks in the future,
• the ability to use existing mounting points and guides.

Condition and service application

The item comes from disassembly and is intended for reinstallation in a vehicle where it is necessary to replace a worn or damaged rear door seal. This type of part is suitable for both post-accident repairs and gradual body restoration when leaks, increased noise, or door closing problems occur. Selecting the right seal for a specific Ford version is facilitated by the manufacturer's markings and assignment to the appropriate product category, which allows for more informed planning of service work and reduces the risk of installing an incompatible part. If you are planning a comprehensive repair or modernization of the door area in your Ford and need other elements from the same group, such as additional edge seals, sill profiles, or pillar seals, check the available parts in the Ford Door seals category. To better understand the impact of body tightness and the condition of rubber elements on acoustic comfort and vehicle system operation, it is worth reading the guide on the exhaust system and accompanying components in the article Performance exhaust system: used manifolds and sports catalytic converters on the road, which covers practical aspects of operation and the selection of used parts.
