Rely on tested quality and order expansion tanks for cooling systems online.

Important function in the cooling circuit

The expansion tank compensates for pressure and temperature differences in the cooling system and thus prevents excess pressure or loss of coolant. It absorbs excess fluid when it heats up and returns it to the circuit when it cools down. As a result, the system remains constantly filled and works efficiently – even with changing loads.

Technology that creates safety

An intact expansion tank protects the engine and cooling system from damage caused by overheating or low pressure. In addition to the storage function, it also takes over the venting of the system. High-quality reservoirs have stable walls, pressure-resistant connections and a tight sealing cap with integrated valve that reliably seals the system.

What should you look out for when buying:

CONNECTIONS

The expansion tank must exactly match the design of your cooling system – including position, connection diameter and fixing points.

CAP VALVE

Make sure that the container has an easy-to-read marking and that the valve in the lid maintains the correct system pressure.

MATERIAL

Select components that are permanently pressure-resistant and temperature-resistant to prevent cracks and leaks during operation.

Reliably protect the engine cooling system!

With a high-quality expansion tank, the cooling circuit remains stable, the pressure constant and the operating temperature within a safe range. Find precisely fitting spare parts in tested quality and protect your cooling system from failure in the long term.
