Purpose and function of the seal

The presented seal is dedicated for installation in the rear left door, where it is responsible for stable window guidance and maintaining a seal between the glass and the door structure. The properly selected shape and flexibility of the rubber help to reduce:

• rainwater ingress into the door interior,
• unwanted wind noise at higher speeds,
• window vibration when driving on uneven surfaces.

This improves the acoustic comfort of the cabin and the durability of the window lifting mechanism.

Construction and material properties

The rubber construction of the seal has been designed for long-term operation in variable weather conditions. The flexible material withstands cyclic loads resulting from opening and closing the doors, as well as the operation of the window in the guide. The properly shaped cross-section ensures:

• stable seating in the door slot,
• even pressure along the entire length of contact with the glass,
• the possibility of repeated removal and installation during service work.

As an original Ford brand component, the seal maintains factory fit parameters, which facilitates installation and minimizes the risk of leaks after replacement.

Benefits of using an original seal

Using a dedicated seal in the rear left door of a Ford Focus Titanium allows for restoring the correct operation of the window and the tightness of the side part of the body. Key advantages include:

• factory fit to the door profile – no need for modifications or trimming,
• consistent appearance with other trim elements,
• reduction of window fogging due to better moisture insulation,
• increased acoustic comfort inside the vehicle.

Replacing a worn or brittle seal is particularly recommended when water streaks appear near the door upholstery, audible wind noise occurs, or there is play in the window guide.

Installation zone and service application

The component is intended for installation in the rear left part of the body, in the area of the door and side window. It can be used both for standard replacement of worn parts and during post-accident repairs, when it is necessary to restore the correct geometry and tightness of the door. Thanks to the preservation of the original geometry, the seal works well with the factory window lifting mechanism and door fittings.
