Automotive Components in the Exhaust System

Decoupling elements are used in the connecting line between the engine and the exhaust post-treatment; these are configured as metal bellows or stripwound hoses. They are used for decoupling movements of mechanical components, expansion and vibration, as well as for compensating for installation tolerances.
