ACV 90000031 anoda HP300 + 2 uszczelki i tuleja

This article is a magnesium anode for the ACV HP300 appliance, supplied with two gaskets and a sleeve. Magnesium anodes protect the enamelled surface of the hot water cylinder by corroding preferentially, thereby preventing pitting and rust on the steel wall. The two gaskets seal the anode threaded fitting and any flanged connection; the sleeve isolates the anode rod from the cylinder wall. All three components are replaced together when the anode is serviced. Anodes of this type are consumable items. The magnesium rod gradually dissolves in the water, and its condition must be checked at every scheduled service. Replacement is due when the rod has lost roughly half its original diameter or shows heavy pitting. Using a gasket that does not match the original thickness can alter the anode position inside the cylinder, reducing protection. The sleeve must be the correct length to keep the rod centred and avoid contact with the cylinder wall, which would short‑circuit the protection. When ordering, confirm that the gaskets and sleeve are included with the anode, as some suppliers list them separately. The part number 90000031 identifies the complete kit; for the anode alone a different code may apply. Always cross‑reference the original component against the catalogue entry for the ACV HP300 to ensure the thread size and rod length are correct.
