Sera External O-Ring for Valve for UVC-Xtreme 800 – Spare

The Sera External O-Ring for Valve (2 pieces) is a genuine replacement part for the Sera UVC-Xtreme 800. Each O-ring seals the external valve connection, ensuring a secure, leak-free fit that keeps your UV-C clarifier running at its best.

Over time, rubber seals harden and lose elasticity, which can cause small leaks or a drop in performance. Keeping a spare Sera External O-Ring for Valve on hand lets you refresh the seal quickly and avoid downtime for your aquarium’s UV-C unit.

Key features of the Sera External O-Ring

• Genuine Sera spare part for the UVC-Xtreme 800
• Set of 2 external valve O-rings

When to replace

Replace the Sera External O-Ring for Valve if you notice leaks around the valve, or as routine maintenance whenever you service or reassemble your Sera UVC-Xtreme 800.

Matching your unit

Two versions are listed, one for the UVC-Xtreme 800 and one for the UVC-Xtreme 1200, so check the model printed on your unit before ordering, as each set is made for its own model. Clean grit and old residue out of the grooves before seating the new rings, and moisten them with tank water so they slide into place without twisting. Keeping a spare set means a leak can be fixed straight away.
