BOSAL 255-383 Rubber Buffer – The Ultimate Exhaust Silencer Solution

The Bosal 255-383 Rubber Buffer is a high‑performance exhaust component designed to reduce vibration, noise and heat transfer between the muffler or catalytic converter and the vehicle’s chassis. Engineered with precision, this buffer delivers superior damping while maintaining optimal exhaust flow.

Key Features & Technical Highlights

• Material Composition: Premium high‑temperature silicone rubber reinforced with a durable elastomer core that withstands temperatures up to 400 °C.
• Vibration Isolation: Engineered geometry provides excellent shock absorption, reducing chassis vibration by up to 70% compared to standard mounts.
• Noise Reduction: The buffer’s unique damping properties cut exhaust noise levels by approximately 5–8 dB in the mid‑frequency range.
• Heat Shielding: Integrated heat‑resistant layer protects surrounding components from thermal damage, extending service life.
• Corrosion Resistance: Chemical additives resist oxidation and corrosion caused by exhaust gases, ensuring long‑term reliability.
• Easy Installation: Designed for quick fitment with standard mounting brackets; no special tools required.

Compatibility & Vehicle Coverage

The 255‑383 buffer is engineered to fit a wide range of models across multiple manufacturers. Below are representative vehicle families and model years where the component is officially supported:

Installation Guide

1. Preparation: Ensure the exhaust system is cool. Remove any existing rubber mounts or brackets that may interfere with the new buffer.
2. Positioning: Place the 255‑383 buffer between the muffler (or catalytic converter) and the mounting bracket. Align the mounting holes precisely to avoid misalignment.
3. Securing: Tighten the mounting bolts to the manufacturer’s torque specification (typically 10–12 Nm). Use a calibrated torque wrench for accuracy.
4. Verification: Inspect the buffer for any gaps or uneven contact. Re‑tighten if necessary and perform a short test drive to confirm vibration reduction.

Maintenance & Longevity Tips

• Inspect the buffer annually for signs of wear, cracking or deformation.
• Avoid exposure to extreme mechanical shocks that could compromise the elastomer integrity.
• If the vehicle operates in harsh environments (salt, sand), consider a protective coating to enhance corrosion resistance.
