Gaskets and pipe connectors: the basis for an efficient flue gas system

A leak-free exhaust system is essential for the performance and environmental compatibility of commercial vehicles. High-quality gaskets on manifolds, flanges and joints prevent hot gases from escaping and protect sensitive components in the engine compartment from thermal overload. Our individual parts in OEM quality have been specially developed for the extreme heat cycles and chemical stresses in the exhaust tract. With precisely fitting pipe connectors, you can ensure that your system remains vibration-resistant and permanently tight, which massively increases the operational safety of your fleet.

Variety of individual parts: From the clamp to the V-band connector

The installation of flue gas components often requires specialized fastening solutions. Whether classic clamps, double clamps or modern V-band pipe connectors – the right choice of connecting element determines the longevity of the entire system. At FZB Fahrzeugbedarf you will find a wide selection of mounting material that is corrosion-resistant and high-strength. Especially when replacing silencers or catalytic converters, the use of new seals and clamps is essential to avoid stress cracks caused by uneven pressure distribution and to reduce noise emissions to a minimum.

What should you look out for when buying:

COMPATIBILITY

The dimensions and shape of the seals and the exact size of the pipe connectors are crucial.

MATERIAL SELECTION

Heat-resistant and durable materials ensure reliable operation in the flue gas system.

LOAD LIMITS

Components have to withstand high temperatures, vibrations and pressure fluctuations in truck operation.

Corrosion resistance and durability of your exhaust components
In harsh winter conditions or during frequent journeys in changing weather conditions, seals and pipe connectors are exposed to extreme chemical stress from road salt and spray water. At the same time, aggressive exhaust gases and enormous temperatures act on the material from the inside. To prevent premature corrosion, we consistently use high-quality materials such as stainless steel and specially galvanized surfaces for our individual parts. This material quality guarantees that the connecting elements remain dimensionally stable even after many years and can be loosened for maintenance purposes if necessary without screws or bolts seizing or tearing off.

Efficient repairs thanks to precisely fitting mounting material
For workshops and fleet managers, time is a crucial economic factor. Nothing is more annoying than a delayed repair because a specific washer or a suitable bracket is missing. Our range of individual parts covers all common diameters and mounting variants for well-known truck brands. The high fitting accuracy of our pipe connectors significantly shortens the installation time and enables stress-free installation of the entire exhaust system. This effectively prevents consequential damage such as vibration cracks and ensures that your commercial vehicle is back on the road as quickly as possible after servicing.

Expert FAQ: Everything about flue gas seals, pipe connectors & installation materials

Exhaust gas seals deform when they are first installed (compression) to compensate for unevenness. When they are reused, this elasticity is no longer present, which almost always leads to leaks.

V-band connectors enable very fast assembly and disassembly with extremely high gas tightness and mechanical stability, ideal for frequently serviced system parts.

Typical signs are black traces of soot in the area of the connection, an altered exhaust noise (whistling or rattling) and a burning smell in the engine compartment.

Galvanized steel or stainless steel are standard. For extreme loads and corrosion protection (road salt), stainless steel is the preferred choice for a long service life.

The outer diameter of the pipes to be connected is always measured. The pipe connector must be precisely matched to this dimension to ensure a force-fit connection.

Leaks upstream of the lambda sensor or the NOx sensor lead to incorrect measurements (false air), which has a negative effect on engine management and leads to increased consumption.

A U-clamp is usually used for simple fixing, while a double clamp (sleeve) connects two pipes with the same diameter in a shock-resistant and tight manner.

Yes, the active regeneration of the particulate filter results in significantly higher temperatures. Special stainless steel multi-layer gaskets are required for this.
