Why is rubber used for exhaust system hangers?

Rubber is used for exhaust system hangers primarily because it effectively isolates noise and vibrations produced by the engine and exhaust system. This isolation is crucial for enhancing the comfort of the vehicle's cabin environment by minimizing unwanted sound transmission. The flexibility of rubber allows the exhaust system to move slightly without transferring excessive force to other components of the vehicle, which can help prevent damage and prolong the lifespan of the exhaust system.

In addition to its noise-dampening properties, rubber allows for thermal expansion of components. As the exhaust system heats up during operation, the materials expand. Rubber hangers can accommodate this expansion and contraction, preventing undue stress on the exhaust components and maintaining proper alignment.

Moreover, while rubber does not prevent rust directly, its presence can indirectly contribute to the longevity of the exhaust system. For instance, if rubber hangers are installed properly, they minimize unnecessary movement and vibration, which can lead to wear and potential exposure to rust-causing elements.

Including all these benefits, it is clear that the use of rubber in exhaust hangers serves multiple essential functions, making it a suitable choice for automotive applications.
