Trucks / buses / transporters

For the On-Highway field, Witzenmann offers flexible metallic elements with connecting parts up to complete pipe assemblies, which, here too, enable optimal solutions under extreme installation conditions.

Applications for trucks, buses and transporters

An overview of our products for trucks, buses and transporters

Witzenmann is the world's leading manufacturer of flexible and rigid pipework components for classic combustion engines (diesel, gas and dual fuel drives). By continuously developing our products, we help to further reduce CO2 emissions.

Upstream Turbocharger Automotive Components
Upstream of the turbocharger

A wide variety of flexible elements, fitted with customer-specific connections, are used before the turbo charger to absorb heat expansions and decouple engine movements and vibrations.
Such as

  • Exhaust gas ducts
  • Ducts in the manifold area
  • Exhaust gas recirculation pipe without microfilter

Downstream Turbocharger Automotive Components

Decoupling elements in the exhaust gas range are temperature and corrosion resistant. Depending on the application, they will be used with or without insulation. Their applications lie in thermo-mechanics (decoupling of vibrations and heat expansions), compensating for mounting inaccuracies or as special elements for dampening structure-borne noise/sound.

Products for these applications are:

  • Decoupling elements
  • Structure-borne noise/sound decoupling elements
  • Stripwound hoses
  • Pipe systems

Fluid Oil systems oil water cooling circuit
Fluid systems

Pipeline systems for liquid circuits such as water, oil and coolant circuits are mostly semi-flexible bellows/smooth-bore tube solutions or custom-fit curved stainless steel pipelines, precisely tailored to the cramped installations conditions close to the engine. Alongside traditional combustion engines, these air-tight pipe systems are increasingly used in E-mobility or hydrogen applications.
