Purpose and Technical Function

The presented fuel filler cap is designed as a closing element for the fuel tank neck in Mercedes compact class vehicles, such as the W177 and W247. It is responsible for securely sealing the filler neck, which limits fuel evaporation and helps maintain proper operating conditions for the fuel supply system. Thanks to its construction conforming to factory Mercedes standards, the cap works with the original thread and seal, minimizing the risk of leaks.

Construction and Material

The cap is made in black, which facilitates its visual integration with the fuel filler area and body elements. The plastic used is resistant to typical operational stresses in the filler area, such as contact with fuel, temperature changes, or frequent opening and closing. The shape and profile of the grip have been chosen to allow for comfortable handling of the cap, even when wearing work gloves.

Mounting Parameters and Compatibility

As a part from the Fuel Filler Flaps and Caps group dedicated to Mercedes, the cap is intended for installation in place of the factory original, without the need for modifications. The appropriate geometry of the seal and fit to the filler neck allow for maintaining proper pressure and tightness within the tank neck. The product has an assigned OEM part number and interchangeable numbers, which facilitates catalog selection and verification of compatibility with a specific vehicle version.

Condition and Service Application

The item is offered in used condition, making it a practical solution for routine maintenance, accident repairs, or supplementing missing components in the fuel filler area. It can be used both as a replacement for a damaged cap and as a part used when completing the entire filler assembly after bodywork and painting repairs.

Technical Support and Part Selection

To correctly select the cap for a specific Mercedes model, it is advisable to use the OEM part number and reference numbers assigned to this model. This helps avoid compatibility issues and ensures proper operation of the fuel system after installation. Additionally, knowing the factory designations makes it easier to search for parts in electronic catalogs and VIN lookup systems.
