This is our MRCE0CAPK6 which uses aluminum as the anode material. For zinc anodes please review MRCE0CZPK6. Offered is a 1.75" 6 pack of full anode assemblies which includes the brass holder and anode. This is the easiest way to replace the anode for your heat exchanger. This is for a 1/4" NPT thread size and will be a drop in replacement for a heat exchanger that has that size anode fitting. These parts will replace any 1.75" E0C product or you can cut it to length if it is shorter. Anodes may not be returned so please be careful when ordering.

If this listing was found paired with a heat exchanger or oil cooler listing, then this zinc will fit the associated part.   If you're looking for a zinc for your part, find that part number and then look for the anode paired with it.    You can purchase that anode by itself. 

Note that that anodes over the years have been call zincs; however, in some cases we offer these anodes in both zinc and aluminum.   Zinc material is best suited for Salt water conditions and aluminum is better suited for brackish or fresh water conditions.   The very best anode material for Fresh water conditions is magnesium, but we currently do not offer anodes in that material. 

If ordered separately, they ship via USPS only the day AFTER they are ordered.  If ordered with a heat exchanger they will go in the box.

If you want to purchase zincs and you are outside of the US, please email orderdesk@mrcool.us and tell us what you're looking for.
