JEGS Anti-Corrosion Plug

JEGS Anti-Corrosion Plug is designed to be used to help protect your cooling system from corrosion. The elements will "attack" the JEGS Zinc Anode Anti-Corrosion plug before (instead of) the aluminum components in your system thus extending their service life. Can be used in most radiators and overflow cans where a drain petcock fitting may be currently installed.
