De Dietrich 7824890 anode D33 mm, L180 mm

This is a magnesium anode from De Dietrich, intended for use in enamelled cylinders within heating systems or water heaters. Anodes of this type protect the cylinder lining from corrosion by acting as a sacrificial element. Over time, the anode material degrades and must be inspected at regular service intervals and replaced when consumed. Selecting the correct anode for a given appliance requires matching the diameter, length, and thread type to the original component, as the anode must fit the cylinder boss and extend fully into the water volume to provide effective protection. This particular article is a De Dietrich anode with a diameter of 33 mm and a length of 180 mm. It is listed under catalogue article 336.112.008 and manufacturer codes 7824890 / 336.112.008. When replacing an anode of this type, ensure that the cylinder is drained sufficiently below the boss level, and that the sealing gasket or thread sealant is renewed to prevent leakage. Always confirm that the replacement anode matches the original dimensions and thread pattern; fitting an anode that is too short or of the wrong diameter will compromise corrosion protection and may cause premature cylinder failure.
