Sacrificial anode
Does anyone know if this type sacrificial anode can be bought anymore? A friend is looking specifically for this type. Years ago he bought them from JC Whitney.
Thanks,
Rich

A sacrificial anode does not have to be elaborate, only has to be a metal with a higher electrochemical potential than the base metal being protected. The sacrificial anode has to be in electrical contact with the base metal, and in contact with the same solution - that is typically the solution from which the bad metal is intended to be protected (typically water, and in particularly sea {salt} water).
All that said, anodes can be purchased or made. The most common are water heater tank anodes, available at your local hardware store. You can also make one out of any appropriate metal, zinc being among the best. I've never seen one like the picture you show.

There is no need for this if you run good antifreeze in your engine/car and changed it according to schedule. Coolant chemistry has improved over the last 50 years...............
PS: I remember these from the 1960's JC Whitney Catalogs.
I actually lived only about 10 miles from their store in South Chicago.Larry

I have kept both gas and electric water heaters for long lives, in part by replacing their anodes before they corrode away.

Thanks for all the input, I'll pass the thread onto the friend I was trying help find a replacement like pictured. I did have a cap anchored sacrificial anode in 62 which did deteriorate.
With new motor, new radiator I do use Zerex G-05.
