Purpose and function of the rear sealing flange

The presented flange operates in the rear zone of the vehicle, where it is responsible for a tight connection of mating components and stable guidance of the working medium. As a part from the Gaskets and sealing rings group, it reduces the risk of leaks, pressure drops, or the ingress of contaminants into critical sub-assemblies. Selecting a flange dedicated to specific models, such as the Golf Mk7, Seat Leon Mk3, or Audi A3 8V, allows for maintaining the factory geometry of connections and the proper operating characteristics of the system. As a result, the system remains stable, and operating parameters are close to the manufacturer's original specifications.

Benefits of using an original Volkswagen component

Using an original component from the Volkswagen brand ensures:

• dimensional compatibility with the factory mounting socket in the rear section of the vehicle,
• repeatable, predictable sealing during long-term operation,
• easier installation without the need for modifications or adjustments to the part,
• consistency with other elements of the sealing system. For workshops and users, this means shorter service time, a lower risk of leaks after installation, and the maintenance of operating parameters in accordance with the vehicle's technical documentation. Stable sealing of the rear zone translates into less wear on cooperating components and a reduction in unplanned vehicle downtime.

Installation characteristics and application in the rear section of the vehicle

The flange has been designed for operation in the area marked as Rear, which facilitates clear assignment to the appropriate vehicle zone when selecting parts. This allows the mechanic to quickly identify the installation location and plan the scope of service work. The component is particularly useful for:

• repairs of systems requiring the restoration of tightness in the rear section of the vehicle,
• servicing after the disassembly of sub-assemblies, where the replacement of sealing elements is recommended,
• preventive replacement during major overhaul work in the rear zone of the car. This approach helps reduce the risk of having to disassemble the same components again in the near future and improves the overall reliability of the system.

Part condition and use in vehicle service

The offered flange is a used component, which makes it an attractive solution for users and workshops looking for an economical alternative while maintaining the original design. Such components work well in maintenance repairs, where fitment to a specific model and maintaining operating parameters close to factory standards are key. Thanks to markings such as SKU and the OEM part number, as well as available interchangeable numbers, the part can be precisely verified against vehicle documentation or catalog software, which minimizes the risk of selecting an incorrect component.

Expanding the sealing system and additional resources

If you are planning a comprehensive repair or upgrade of the sealing area in your Volkswagen and need other elements from the same group, such as additional flanges, rings, or gaskets cooperating with rear sub-assemblies, check the available parts in the Volkswagen Gaskets and sealing rings category.
