Purpose and Body Fitment

The presented seal has been specifically prepared for installation on the rear, left side of the sliding side door in W447 series models. Its placement on the vehicle is clearly defined, which facilitates the selection of the correct part for body repairs and eliminates the risk of errors during installation. Original origin from the Mercedes brand means that factory dimensional tolerances are maintained, which is important for proper door operation and passenger cabin sealing.

Technical and Functional Characteristics

The seal operates in the critical contact area between the sliding door and the body, where it is exposed to frequent opening and closing and varying weather conditions. The element's design has been developed to:

• limit the penetration of water and dirt into the vehicle's interior,
• reduce air noise during driving at higher speeds,
• support stable closing and operation of the sliding door,
• maintain flexibility over a wide range of operating temperatures.

By maintaining the correct profile and material hardness, the seal works with the factory guides and locks, which promotes even pressure around the entire door perimeter.

Condition of the Part and Benefits of Using a Used Part

The offered seal is in the category of used parts, which allows for economical vehicle repair while maintaining the original manufacturer's specifications. Compared to non-factory aftermarket parts, using a dismantled element often provides a better fit to the body and more predictable performance during operation. This is a practical solution for replacing worn or damaged seals when maintaining the factory installation standard is important.

Installation and Service Application

The seal is designed for direct installation in place of the factory element on the rear, left side of the sliding door. With a properly prepared body surface, the replacement process is a typical service operation, which can be performed in a body repair workshop or a specialized brand service center. Using an original seal reduces the need for additional adjustments, which shortens work time and reduces the risk of leaks after installation.

Selection Support and Additional Information

If you are planning a comprehensive refurbishment of the sliding door area, it is worth considering a simultaneous check of other seals and guide elements to restore the full functionality of the entire system in one service operation.
