Bosal 255-172 Rubber Buffer, silencer

Product Overview

The BOSAL 255-172 Rubber Buffer, commonly referred to as a silencer or exhaust rubber strip, is a precision‑engineered component designed to enhance the performance and longevity of automotive exhaust systems. This part serves as an essential mounting element, providing vibration isolation, secure attachment, and protection against corrosion for the muffler assembly.

Key Functionalities

• Vibration Dampening: The rubber construction absorbs engine vibrations, reducing noise transmission to the vehicle chassis and improving overall ride comfort.
• Secure Mounting: It acts as a resilient clamp that holds the muffler firmly in place, preventing movement during acceleration, braking, or rough terrain driving.
• Corrosion Resistance: The material is formulated to withstand high temperatures and exhaust gases, extending the life of the exhaust system by shielding metal components from oxidation.
• Easy Installation: Designed with a simple clamp‑and‑lock mechanism, it can be installed or replaced without specialized tools, making it ideal for both professional mechanics and DIY enthusiasts.

Material Composition

The BOSAL 255-172 is crafted from high‑grade silicone rubber, chosen for its exceptional heat tolerance (up to 250 °C) and chemical stability. The silicone matrix incorporates reinforcing fillers that maintain structural integrity under repeated thermal cycling, ensuring consistent performance over thousands of miles.

Compatibility Matrix

This buffer is engineered to fit a wide range of vehicles, particularly those within the Citroën, Peugeot, and DS families. Common models include:

• Citroën C3 I & II
• Citroën C2 (JM)
• Peugeot 1007 (1.4L, 1.6L)
• DS DS3 (SA_ 1.6 2015‑2019)

For each vehicle, the buffer is available in single or dual‑piece configurations to accommodate different exhaust layouts.

Installation Guide

1. Preparation: Ensure the muffler and mounting brackets are clean and free of debris. Inspect for any damage that might compromise fitment.
2. Positioning: Place the BOSAL 255-172 between the muffler flange and the exhaust pipe or bracket, aligning it with the designated holes.
3. Securing: Tighten the clamp bolts evenly to distribute pressure across the rubber strip. Avoid over‑tightening, which could deform the silicone.
4. Verification: Check for any gaps or misalignments. The buffer should sit flush against both surfaces, providing a smooth seal.

Maintenance Tips

• Inspect annually for signs of wear such as cracking, discoloration, or loss of elasticity.
• Avoid exposure to extreme cold temperatures that could cause the rubber to become brittle; store in a temperature‑controlled environment when not in use.
• If the buffer shows any degradation, replace it promptly to maintain optimal exhaust performance and prevent metal fatigue.

Performance Benefits

By integrating the BOSAL 255-172 into an exhaust system, vehicle owners experience:

• Reduced Noise Levels: The buffer’s vibration isolation properties lower cabin noise by up to 3 dB.
• Improved Exhaust Flow: Secure mounting eliminates air leaks that can disrupt exhaust backpressure, preserving engine efficiency.
• Extended Component Life: Protection against heat and corrosion delays the onset of rust on muffler housings and brackets.
