Eheim Set of O-Rings for Double Tap Unit 2 Pack – Professional II 2026 / 2028 / 2126 / 2128 (7444190)

The Eheim O-Ring Set (7444190) is a genuine OEM replacement set of two rubber O-rings designed to seal the double tap unit to the canister body on the Eheim Professional II (2026 / 2028) and Professional IIe (2126 / 2128) external canister filters. These O-rings create the watertight seal between the double tap valve assembly and the filter canister — preventing leaks at the tap connection during normal filter operation.

Over time rubber O-rings harden, crack, and lose their sealing ability — particularly after repeated disconnection and reconnection of the double tap unit during filter maintenance. Replacing with a genuine Eheim OEM set is the simplest and most cost-effective way to restore a reliable, leak-free seal. Eheim recommends replacing double tap O-rings once a year as part of routine filter maintenance.
