Exhaust Gas Decoupling Elements Image Text
Automotive Components in the Exhaust System

In the area of exhaust gases, ducts and decoupling elements or expansion elements of different design absorb vibrations, heat expansions or engine motions and decouple these from other systems.

The hose joint absorbs oscillations and motor vibrations. It is corrosion-resistant, thanks to an appropriate selection of materials. Depending on the installation conditions, the flexible elements for exhaust gas systems will be produced with a round or oval shape.

Hose assemblies are among the products used most frequently for decoupling of vibrations. They are fitted preferentially in the pre-tube area close to the engine. Two different hose joint designs are available: the LIS liner for standard applications and the LIH liner for use when installation space is tight.
