ACV 90448255 kit 2 anodes vert.32x400 LCA

The ACV 90448255 kit 2 anodes vert.32x400 LCA is a set of two magnesium anodes intended for the cathodic protection of enamelled steel cylinders in heating systems. Anodes of this type are sacrificial; they corrode preferentially to the cylinder lining, preventing pitting and rust formation. They are consumable items that must be inspected at every service interval and replaced when the core is exposed or the mass has reduced significantly. Such anodes are selected by overall length, diameter, and thread type, which must match the original cylinder tapping. The vertical orientation indicated by the product name suggests that these are installed in a cylinder with the anode rod descending from the top connection. When replacing anodes, ensure the new rod clears the bottom of the vessel and does not contact internal fittings. The 32x400 designation refers to the anode dimensions, though the exact thread specification should be confirmed against the existing part. Magnesium anodes are standard for most residential and light commercial cylinders; in areas with very hard water or aggressive chemistry, aluminium or zinc anodes may be specified instead. Always check the cylinder manufacturer’s service manual for the correct replacement interval and torque.
