Eheim Set of Sealing Rings for Prefilter and Canister – Professional 3 2071 / 2073 / 2075 (7428770)

The Eheim Sealing Rings Set (7428770) is a genuine OEM replacement set containing two critical sealing rings for the Eheim Professional 3 external canister filter range — one sealing ring for the prefilter and one for the filter canister body. Together, these rings form the primary watertight seals that prevent water leaks during filter operation.

This is one of the most important maintenance spare parts you can keep on hand for any Eheim Professional 3, 3e, or 4+ filter. Over time both rubber rings harden, crack, and lose their sealing ability — particularly after repeated disassembly during routine maintenance. Replacing with a genuine Eheim OEM set ensures exact fit, a reliable watertight seal, and full protection against costly leaks and flooding.

Key Features

• Genuine Eheim replacement part: Exact OEM fit for Professional 3, 3e, and 4+ canister filters — no compatibility guesswork
• Two sealing rings included: One ring for the prefilter + one ring for the filter canister — a complete set covering the two primary leak points on the filter
• Prevents leaks and flooding: Replaces hardened or cracked sealing rings that are one of the most common causes of canister filter leaks
