BOSAL 255-853 Rubber Buffer – The Ultimate Exhaust Silencer

The Bosal 255‑853 Rubber Buffer is a high‑performance component designed to reduce exhaust noise, protect the vehicle’s exhaust system, and enhance overall driving comfort. Crafted from premium elastomeric material, this buffer delivers reliable vibration damping and acoustic attenuation for a wide range of passenger cars.

Key Features

• Superior Noise Reduction: The rubber construction absorbs sound waves generated by the exhaust flow, resulting in a noticeably quieter cabin experience.
• Vibration Dampening: By isolating the exhaust system from chassis vibrations, the buffer prolongs the life of mounting brackets and other components.
• High‑Temperature Resistance: Engineered to withstand continuous exposure to exhaust gases up to 400 °C without degradation.
• Easy Installation: The buffer’s compact size (60 mm × 57 mm) and standardized mounting points allow for straightforward fitting on most front‑mounted exhaust manifolds.
• Durable Construction: Made from a reinforced rubber compound that resists cracking, oil leakage, and chemical attack.

Design & Material Composition

The buffer’s core is composed of a high‑density silicone‑rubber blend. This material offers excellent elasticity while maintaining structural integrity under thermal stress. The outer layer incorporates a protective coating that prevents oxidation and extends service life.

Its shape features a semi‑circular profile with an integrated flange, ensuring a snug fit against the exhaust manifold’s surface. The design also includes strategically placed venting slots to facilitate airflow and prevent pressure buildup.

Compatibility & Vehicle Applications

The Bosal 255‑853 Rubber Buffer is engineered for use on a variety of front‑mounted exhaust systems, particularly those found in:

• Volkswagen models such as the Golf I (17), Golf II (19E/1G1), and Polo Coupe.
• Audi variants including the Audi 80, Audi 100, and A6 series.
• Skoda models like the Felicia I and Favorit.
• Lada Samara 1.3 L, 1.5 L, and 1.1 L engines.
• Seat Terra and Toledo I platforms.
• DaeWoo Leganza 2.0 L 16‑V models.

These applications cover a broad spectrum of vehicles that share similar exhaust manifold dimensions, making the buffer a versatile choice for automotive enthusiasts and technicians alike.

Installation Guide

1. Preparation: Clean the exhaust manifold surface to remove oil, rust, or debris. Ensure the area is dry before proceeding.
2. Positioning: Place the buffer onto the manifold, aligning the flange with the mounting groove. The venting slots should face outward for optimal airflow.
3. Securing: Use the supplied mounting hardware or standard bolts to secure the buffer in place. Tighten evenly to avoid distortion of the rubber material.
4. Final Check: Verify that the buffer sits flush against the manifold and that no gaps remain. Inspect for any signs of misalignment before starting the engine.

Maintenance Tips

• Inspect the buffer periodically for cracks, bulges, or oil seepage. Replace immediately if any damage is observed.
• Avoid exposure to harsh chemicals such as brake fluid or antifreeze, which can degrade rubber over time.
• Keep the exhaust system clean; accumulation of soot can increase pressure on the buffer and accelerate wear.

Performance Benefits

By integrating the Bosal 255‑853 Rubber Buffer into your vehicle’s exhaust setup, you gain:

• A measurable reduction in cabin noise levels, enhancing passenger comfort.
• Lower vibration transmission to the chassis, which can improve handling and reduce wear on suspension components.
• Improved durability of exhaust mounting brackets due to reduced mechanical stress.
