Genuine Eberspacher (Espar) 24mm to 30mm exhaust adapter L bend, designed to connect a 24mm exhaust outlet to a 30mm exhaust pipe. This exhaust adapter elbow (exhaust reducer / exhaust pipe connector) is commonly used in marine diesel heater exhaust systems where a water drain coil is required to manage condensation and ensure reliable operation.
Eberspacher Exhaust Adapter L Bend – 24mm to 30mm (1" to 1.25")
This genuine Eberspacher adapter allows a secure transition from 24mm to 30mm exhaust systems while adding a 90-degree bend for easier routing. It is ideal for diesel heater exhaust setups, including Espar and Webasto systems, where you need to connect different exhaust sizes and integrate a water drain for moisture control.
The 30mm side corresponds to approximately 1.25 inches (commonly referred to as 1-1/4"), making it suitable for both metric and US-based exhaust setups.
This adapter is commonly used with heaters such as Eberspacher / Espar D2, D2L, D4, D4L, D4R, and D5, which typically use a 24mm (approximately 1 inch) exhaust outlet.

Espar / Eberspacher Adapter Exhaust L Bend 24mm - 30mm

Perfect fit
Needed this part to connect my 24mm exhaust output to an existing 30mm host on my heater replacement project. This part fit perfectly. A little annoyed I paid 20 for two day shipping, but it was more than a week before the product even posted. Still, fit my timeline and the project completed on time.

essential
I used simple cut in the pipe for my espar exhaust, with this buddy my installation is much cleaner now. The pipe that screws on the top is quite expensive tho
