O-ring seals for valves, sera UVC-Xtreme 1200 — set of 2

These replacement O-ring seals are designed for the external valve connections of the sera UVC-Xtreme 1200 unit. Supplied as a set of 2, the O-rings restore the water-tight seal at valve joints, helping to prevent leaks and maintain correct flow control in the UVC system. Made to match the valve interface of the named model, the seals are intended for routine maintenance and timely part replacement to preserve reliable operation.

Advantages

The O-ring set provides a direct-fit solution for the valve connections on the specified UVC unit, enabling quick replacement without special tools. These seals reduce the risk of external leaks and associated downtime, helping to maintain stable hydraulic performance of the device. Supplied as a pair, the set allows replacement of both connection points at once to ensure consistent sealing and balanced wear.

Suitable for

• Routine maintenance of the sera UVC-Xtreme 1200 valve connections
• Replacement of worn or damaged valve O-rings to stop external leaks
• Restoring water-tight performance after disassembly or transport

Key specifications

• Quantity: set of 2 O-rings
• Function: sealing external valve connections to prevent leaks
• Compatibility: designed for valve interfaces of the sera UVC-Xtreme 1200 unit
• Material: elastomeric sealing compound suitable for freshwater systems

How to use

Turn off and disconnect the UVC unit and relieve any pressure before attempting replacement. Remove the valve connections according to the device manual, extract the old O-rings and clean the sealing grooves of debris and residue. Lightly lubricate the new O-rings with a water-compatible silicone lubricant or manufacturer-recommended sealant, position them in the grooves, and reassemble the valves ensuring even seating. After reassembly, run a leak check by operating the unit and inspecting the external connections.

Usage recommendations

Inspect O-rings during scheduled maintenance intervals and replace at the first sign of cracking, flattening, or persistent seepage. Use only non-petroleum-based lubricants that are safe for aquarium and freshwater equipment to avoid material degradation. Store spare O-rings in a cool, dry place away from direct sunlight to preserve elasticity.
