Flex-a-Lite Extruded Aluminum Expansion and Overflow Tanks

Flex-a-Lite’s Extruded Aluminum Expansion and Overflow tanks are designed to be used either as an expansion tank or overflow canister. When used as an expansion tank coolant can be drawn from the tank back into the radiator as the system cools and when used as an overflow the tank contains any fluid that escapes the pressurized radiator cap when high temperatures are encountered.
