Rely on tested quality and order your catalytic converters and accessories directly online.

Reduce emissions, ensure performance

A high-performance catalytic converter is at the heart of modern exhaust gas aftertreatment in commercial vehicles. It ensures that harmful nitrogen oxides and particulates are efficiently reduced in order to meet the strict Euro 6 standards. Whether you need a new SCR catalytic converter or are looking for the right catalytic converter accessories such as gaskets and mounting kits – at FZB Fahrzeugbedarf we rely on OEM quality. Our components are specially designed for the high thermal loads in long-distance traffic, guarantee an optimum fit and ensure the long-term operating license of your truck fleet.

High-quality accessories

Our range includes all components of the catalytic converter system: catalytic converters, retrofit kits, manifolds, chargers, assembly kits, regeneration kits for soot/particle filters, silencers and sensors. All parts are characterized by high precision, durability and temperature resistance. Thanks to the exact fit of the spare parts, you can quickly maintain or repair your exhaust system, minimize downtimes and ensure the full performance of your truck.

SCR catalytic converters: Efficient exhaust gas purification for Euro 6 engines
Modern SCR technology (Selective Catalytic Reduction) is now standard to massively reduce NOx emissions. In combination with urea injection, the catalytic converter converts nitrogen oxides into harmless nitrogen and water. As these components are coated with valuable precious metals on the inside, the quality of the ceramic or metal monoliths is crucial for the conversion rate. High-quality accessories, such as heat-resistant clamps and special sealing rings, ensure that the system remains absolutely gas-tight and that the sensors deliver correct values to the engine management system.

Avoid defects: Tips for catalytic converters and accessories
A clogged or damaged catalytic converter inevitably leads to a loss of power and increased fuel consumption. Common causes are low-quality fuel, errors in AdBlue dosing or mechanical vibrations due to defective flex pipes. When replacing a catalytic converter, it is essential to check all the catalytic converter accessories. New pipe connectors and brackets prevent stress cracks and ensure that the expensive exhaust component is mounted vibration-free. At FZB, you will find everything you need for a professional repair from a single source.

It converts harmful exhaust gases such as nitrogen oxides, carbon monoxide and hydrocarbons into less harmful substances through chemical reactions.

Euro 6 systems are significantly more complex and usually combine SCR catalytic converters with particulate filters in order to comply with the much stricter NOx limits.

Signs are loss of power, error messages in the cockpit (exhaust warning light), increased consumption or a rattling noise in the exhaust tract.

In some cases, professional cleaning is possible, but in the event of mechanical damage to the monolith or chemical ageing, replacement is unavoidable.

Seals and clamps lose their clamping force due to extreme heat. Only new installation material guarantees an absolutely tight system.

The SCR catalytic converter uses AdBlue to enable the chemical reaction for nitrogen oxide reduction. No cleaning takes place without AdBlue.

In most cases, unburned fuel enters the exhaust tract, which ignites in the catalytic converter and generates temperatures above the melting point of the ceramic.

We stock catalytic converters and matching accessories for all common brands such as MAN, Mercedes-Benz, Scania, Volvo and many more in OE quality.
