Below you will find expansion containers in several variants and colors. We have several types of expansion tanks in different sizes. The expansion tank is used for mounting in the engine compartment of a car, the tank allows the coolant to expand and contract again. These containers are sold as universal containers, ie. for mounting in racing cars for motorsport or a project car for you to rebuild yourself. Cooler lids with cover valves are often included so that it closes too much pressure out to the radiator system.
