Overflow tank with dome end

15" black

$109.00

Black over brass overflow tank on 2" diameter with dome end and adjustable mounts.  Made in the USA

Here is how it works...should the system pressure exceed the cap’s rating, the spring will compress and fluid will flow through the upper tube to fill the expansions tank.

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 into the cooling system as the engine cools down.

Contact us directly for alternative sizes, finishes shapes or anything cool you want made.


We make to order. Please allow adequate time for us to build.
