Eheim Set of Sealing Rings and Screws for ReeflexUV 350 / 500 / 800 (7481300)

The Eheim Sealing Rings Set (7481300) is a genuine OEM replacement set containing sealing rings and 2 screws designed specifically for the Eheim ReeflexUV 350, ReeflexUV 500, and ReeflexUV 800 UV sterilisers. The sealing rings create the watertight seal inside the ReeflexUV housing — preventing leaks around the UV lamp chamber and ensuring safe, correct operation of the steriliser.

During routine UV lamp replacement or steriliser maintenance, the sealing rings should be inspected and replaced if they show any signs of wear, cracking, or deformation. Replacing with a genuine Eheim OEM set ensures a correct fit and a reliable, leak-free seal every time.
