-4/-6 AN Fitting Type

This A5052 aluminum Carbing Reservoir Tank is designed to reduce the amount of air bubbles in the water cooling system, and thereby prevent overheating. At high engine RPM, the water pump can create aeration and cavitations (tiny air bubbles in the coolant), and can debilitate its ability to cool. The Carbing Reservoir Tank includes three ports and a pressurized cap. Carbing Reservoir Tank is available in two different port sizes, I.D.4/I.D.6 and I.D.6/I.D.8.
