Witzenmann products are delivered to all reputable automotive and system manufacturers today.
For the exhaust gas area, decoupling elements or expansion elements of different designs are manufactured that decouple vibrations, heat expansion or engine movements. Flexible exhaust gas re-circulation lines contribute significantly to improved pollutant emissions, and the formation of nitrogen oxides in the combustion process is reduced.
In oil, fuel and cooling circuits, the advantages of flexible metal lines include their absolute gas and diffusion tightness, long service life and temperature resistance. This is an essential criterion, especially when they are routed close to exhaust manifolds, turbochargers or the exhaust system.
