BOSAL 255-624 Rubber Buffer – The Ultimate Exhaust Silencer

The Bosal 255-624 Rubber Buffer is a high‑performance exhaust silencing component designed to reduce noise, vibration, and harshness (NVH) while maintaining optimal engine breathing. Engineered with precision, this buffer delivers superior acoustic dampening for a wide range of vehicles, from compact cars to light commercial vans.

Key Functional Features

• Acoustic Dampening: The rubber construction absorbs sound waves generated by exhaust gases, significantly lowering overall vehicle noise levels.
• Vibration Isolation: By acting as a flexible mount, the buffer reduces vibration transmission from the exhaust system to the chassis and body panels.
• Heat Resistance: Made from high‑temperature rubber compounds, it withstands exhaust temperatures up to 400 °C without degradation.
• Corrosion Protection: The material resists oxidation and rust, extending service life even in harsh environmental conditions.
• Easy Installation: Designed with a universal mounting profile that fits standard exhaust brackets and clamps across multiple vehicle platforms.

Material Composition

The buffer is fabricated from a proprietary blend of natural and synthetic rubber, reinforced with carbon black for added strength. This composition ensures:

• High tensile durability to endure repeated thermal cycling.
• Excellent elasticity for consistent sealing against exhaust gases.
• Low compressibility to maintain structural integrity under load.

Compatibility Overview

The Bosal 255-624 Rubber Buffer is engineered to fit a broad spectrum of vehicles. Below are representative models and series where this component is commonly used:

• MAZDA E‑SERIE, B‑SERIE (2.0 L & 2.2 L)
• NISSAN VANETTE, MICRA I, SUNNY I
• CHRYSLER NISSAN platforms with 20650V5200, 20650D0100, and 2066091P00 exhaust configurations.
• Various pickup and light commercial vehicle chassis requiring a universal rubber buffer solution.

Installation Guidelines

1. Preparation: Clean the mounting area of any debris or corrosion. Ensure the exhaust pipe is free from oil residue.
2. Positioning: Place the buffer between the exhaust pipe and the mounting bracket, aligning it with the designated slots.
3. Securing: Fasten using standard bolts or clamps provided with the vehicle’s exhaust system. Tighten to manufacturer torque specifications.
4. Verification: After installation, check for any gaps or misalignments that could compromise acoustic performance.

Performance Benefits

• Noise Reduction: Users report up to a 30 % decrease in cabin noise levels during idle and cruising conditions.
• Improved Comfort: Reduced vibration translates into smoother ride quality, especially noticeable on long drives.
• Enhanced Durability: The buffer’s heat‑resistant properties prevent premature wear of surrounding exhaust components.

Maintenance Tips

While the Bosal 255-624 Rubber Buffer is designed for long life, routine checks can further extend its performance:

• Inspect annually for signs of cracking or hardening.
• Reapply a high‑temperature silicone sealant if minor gaps appear.
• Avoid exposure to extreme chemical solvents that may degrade rubber integrity.
