Genuine Webasto 22mm Flexible Exhaust Pipe

The Webasto 50900126A is a genuine 22mm flexible stainless-steel exhaust pipe for compatible Webasto fuel-fired auxiliary heaters.

The pipe provides a flexible exhaust path from the heater toward the designated exhaust termination point.

With a length of 1 meter, the 50900126A can be used in compatible new installations as well as heater exhaust-system service and replacement applications.

Stainless-Steel Construction

The Webasto 50900126A is manufactured from stainless steel for use within the heater exhaust system.

Its flexible construction allows the exhaust tube to be routed as required by the compatible heater installation.

Because exhaust-system routing is installation-sensitive, always follow the requirements for the specific Webasto heater and vehicle.

22mm Exhaust Connection

The 50900126A is designed for compatible heaters using a 22mm exhaust connection.

Both the heater exhaust outlet and associated exhaust hardware should be verified before ordering.

The important identifiers are:

• Webasto 50900126A
• 22mm exhaust size
• 1-meter length
• Stainless-steel flexible construction
• End cap included

One Meter Long

The Webasto 50900126A is supplied in a 1-meter length.

This is approximately 39.4 inches and is commonly described as approximately 40 inches in parts listings.

For BTRAC product specifications, I recommend using the manufacturer’s metric dimension of 1 meter as the primary measurement.

End Cap Included

The Webasto 50900126A is supplied with an end cap.

This is an important distinction when comparing flexible exhaust tubing from different Webasto configurations.

Verify the complete installation requirements before ordering additional clamps or exhaust-system hardware.

Air Top 2000 Applications

The Webasto 50900126A is documented for compatible heaters within the Air Top 2000 family, including:

• Air Top 2000 S
• Air Top 2000 ST
• Air Top 2000 STC

This makes the exhaust pipe a natural addition to BTRAC’s growing Webasto Air Top service-parts catalog.

Thermo Top Evo Applications

The 50900126A is also documented for compatible Thermo Top Evo heaters.

BTRAC carries the complete Webasto Thermo Top Evo 12V diesel coolant heater kit, giving this exhaust component a strong connection to the complete heater system.

Customers servicing an existing Thermo Top Evo can navigate from the complete heater into fuel, controls, diagnostics, and exhaust-system components.

Additional Webasto Applications

Documented applications also include compatible:

• Thermo Pro 50 Eco
• Thermo Top Z/C
• Thermo 50

Because the 50900126A serves multiple Webasto heater families, it belongs primarily under the exhaust-system category rather than being limited to a single heater-model category.

Part of the Complete Heater Exhaust System

The flexible exhaust pipe is one component within a heater exhaust installation.

Depending on the heater and application, the exhaust system can include:

• Heater exhaust outlet
• Flexible exhaust pipe
• Exhaust clamps
• Exhaust mounting hardware
• Exhaust silencer or muffler
• Exhaust termination components

Individual components should be selected according to the specific heater and installation requirements.

Build the Webasto Catalog Around Complete Systems

BTRAC carries a growing selection of Webasto auxiliary-heater service components spanning:

• Exhaust systems
• Fuel systems
• Combustion systems
• Coolant systems
• Heater controls
• Sensors and electrical components
• Diagnostic equipment
• Complete heater systems

The 50900126A provides a useful cross-family exhaust-system page connecting several different Webasto heater platforms.
