This tube design provides equal volumetric throughput but increases tube surface area by 293% thus requiring fewer tubes and still achieving better heat exchange

We designed this pie-shaped overflow tank to nest against the sidewall and fit inside the  1930-32 Ford Radiator shell

The highly elliptical tube shape provide equal volumetric throughput but increase surface area by 293% thus requiring fewer tubes and still providing greater heat exchange

It is made of polished brass, 3" diameter, copper top and yes, it is made in the USA Should the system pressure exceed the caps rating, the spring will compress and fluid will flow through the upper tube to fill the chamber. In the event the recovery tank reaches capacity, the fluid will find the second tube and exit to the street. A vacuum will draw the coolant back
