Mercedes C117 X117 Bonnet Hood Seal Gasket Rubber Right O/S A1178800297

Mercedes C117 X117 Bonnet Hood Seal Gasket Rubber Right O/S is a precisely fitted body component designed to operate on the right side of the engine bay. It is responsible for the tight fit of the hood, limiting the ingress of water, dirt, and noise, and maintaining the stable position of the panel. Thanks to the use of original geometry, the seal ensures proper alignment of the hood with the bodywork and supports the maintenance of the vehicle's correct aerodynamics.

Purpose and technical function

The right hood rubber seal is dedicated to the C117 and X117 series models, where it is responsible for sealing the contact between the hood and the body structure on the right side. This component limits air drafts, reduces the ingress of contaminants into the engine bay, and helps maintain a stable hood line relative to the fenders and bumper.

A properly selected seal from the Seals and sealing rings group contributes to:

• increasing the protection of components in the engine bay against moisture and dirt,
• reducing wind noise at higher speeds,
• maintaining even gaps between the hood and the bodywork.

Construction and placement on the vehicle

The element is made of flexible rubber material, adapted to work in variable temperature conditions and under constant mechanical loads resulting from opening and closing the hood. The design of the seal has been molded to accurately replicate the shape of the hood edge and adjacent body elements.

Placement on the right side of the vehicle allows for precise guidance of the sealing line along the edge of the hood, which is crucial for maintaining visual consistency and correct distribution of clamping forces. As a result, the hood closes in a repeatable manner, and the seal works with the locks and hinges without excessive stress.

Performance parameters and benefits of installation

A properly selected hood seal affects the comfort of vehicle operation and the durability of components located in the engine bay. Installing this component allows you to:

• limit corrosion of metal elements in the front zone,
• reduce the risk of water and mud accumulation in critical structural points,
• improve the vehicle's refinement by reducing noise from the hood area.

The product is intended for Mercedes vehicles, which ensures compatibility of shape and mounts with the manufacturer's factory solutions. Thanks to this, the installation is predictable and does not require interference with the body structure.

Condition and service application

The item is offered as a used part, which allows for an economical replacement of the seal while maintaining compliance with the vehicle's original specification. This type of component is particularly useful for post-accident repairs, correcting hood alignment, or removing the effects of operational wear of factory seals.

In workshop practice, replacing the right hood seal is recommended when cracks, permanent deformations, or loss of material elasticity are visible, which can lead to leaks and increased noise while driving.

Complementary Mercedes sealing elements
