Ford Kuga C520 Door Weatherstrip Rubber Gasket Seal Rear Left N/S CJ54-S25325-AE

Ford Kuga C520 Door Weatherstrip Rubber Gasket Seal Rear Left N/S is an original body component designed for the rear left door area of the Ford Kuga C520 generation. The carefully engineered rubber profile ensures a tight door seal, improves acoustic comfort, and reduces moisture ingress into the vehicle interior. By maintaining factory geometry, the seal guarantees proper fitment to the bodywork edges and stable interaction with the lock and hinges.

Purpose and function of the seal

The presented seal belongs to the Door seals category and is dedicated to installation in the rear left part of the Ford Kuga C520 body. Its task is to create a flexible barrier between the door edge and the body frame, which translates into reduced road noise, wind noise, and the ingress of water and contaminants into the passenger cabin. The properly selected hardness of the rubber compound and the cross-sectional profile allow for even pressure on the seal when closing the door, without placing excessive load on the hinges. As a result, the door closes smoothly, and the contact line remains stable during vehicle operation.

Construction and technical properties

The seal is made of a flexible rubber material with parameters selected for operation in variable weather conditions. The design ensures elasticity is maintained across a wide temperature range, which reduces the risk of cracking and loss of sealing properties during long-term use. Key functional features:

• profile matched to the shape of the rear left door edge of the Ford Kuga C520,
• stable adhesion to the bodywork after proper installation,
• reduction of air drafts at higher speeds,
• protection against the ingress of water and fine contaminants into the door interior and cabin. Thanks to the preservation of factory geometry, the component works well with original mounting points, which facilitates installation and allows for consistency with other body seals.

Vehicle placement and installation

The seal is intended for installation in the rear left part of the vehicle, in the passenger door area – depending on the body configuration. Such placement requires precise routing of the seal along the entire perimeter of the door opening, while maintaining the continuity of the contact line. During installation, it is recommended to:

• thoroughly clean the contact surface of dirt and old seal residues,
• check the condition of the sheet metal edges for corrosion and deformation,
• gradually seat the seal along its entire length without overstretching the material,
• check the door closure after installation to confirm even pressure. A properly installed seal supports the maintenance of correct door geometry and helps minimize the risk of rattling, squeaking, and leaks during operation.

Characteristics of the used component

The offered item comes from the secondary market, which means it is a used part that retains functionality consistent with its intended purpose. This type of component is a beneficial solution for users looking for original body parts at a reasonable price, while maintaining compliance with the vehicle's factory specifications. Choosing a used door seal allows for reduced service costs during post-accident repairs, replacement of worn components, or restoring body tightness after years of operation. At the same time, material and structural consistency with other seals in the vehicle is maintained.

Selection support and additional information

If you are planning a comprehensive repair or upgrade of the door area in your Ford and need other elements from the same group, such as edge seals, frame seals, or additional protective profiles, check the available parts in the Ford Door seals category. When deciding to use parts from the secondary market, it is worth knowing practical tips on optimizing service costs and making safe component choices.
