BOSAL 255‑191 Rubber Buffer – The Quiet Guardian of Your Exhaust

The BOSAL 255‑191 Rubber Buffer is a precision engineered component designed to enhance the performance and longevity of your vehicle’s exhaust system. Whether you’re looking to reduce vibration, dampen noise, or protect critical mounting points, this buffer delivers reliable results across a wide range of automotive applications.

Key Functionalities

• Vibration Isolation: The rubber construction absorbs engine and exhaust vibrations, preventing them from transferring to the chassis or body panels. This leads to smoother operation and reduced wear on surrounding components.
• Noise Reduction: By acting as a secondary muffler element, the buffer helps lower overall exhaust noise levels, contributing to a quieter cabin experience.
• Thermal Protection: The material’s inherent heat resistance shields mounting brackets and nearby parts from high temperatures generated by the exhaust gases.
• Corrosion Resistance: Designed with durable rubber compounds, it resists oxidation and corrosion even in harsh environmental conditions.

Material Composition

The buffer is crafted from a high‑performance synthetic rubber blend that offers excellent elasticity, heat tolerance up to 250 °C, and resistance to oil, coolant, and brake fluid. This composition ensures consistent performance over the lifespan of the vehicle.

Installation Overview

Installing the BOSAL 255‑191 is straightforward:

1. Remove Existing Mounting: Detach any old rubber or metal brackets from the exhaust system.
2. Position the Buffer: Place the new buffer between the exhaust pipe and the mounting bracket, aligning it with the designated slots.
3. Screw Securely: Fasten the bracket using the supplied bolts. Tighten to the manufacturer’s torque specifications.
4. Check Alignment: Ensure the buffer sits flush against both surfaces and that no gaps remain.

Compatibility Matrix

The BOSAL 255‑191 is engineered for a variety of models, particularly within the Peugeot and Citroën families. Below is an illustrative list of compatible vehicles:
