Eheim Set of Sealing Rings for Adapter and Screen – Professional 3 & 3e 2076 / 2078 (7428680)

The Eheim Sealing Rings Set (7428680) is a genuine OEM replacement set of sealing rings designed for the adapter and separation screen of the Eheim Professional 3 and Professional 3e external canister filters. These rings create watertight seals at the adapter and screen connection points inside the filter — preventing leaks and ensuring reliable, correct filter operation.

Over time sealing rings can harden, crack, or deform — particularly with repeated removal and reassembly during routine filter maintenance. Replacing with a genuine Eheim OEM set ensures an exact fit and a reliable, long-lasting watertight seal.
