## Long description

Replacement O-ring seal set designed for sera 400 HO and 600 S aquarium filters. This set provides the sealing rings needed to restore watertight connections in filter housings and pump assemblies during routine maintenance or repair.

The O-ring materials are chosen to resist common aquarium conditions and provide reliable compression and sealing over repeated maintenance cycles. By replacing worn or damaged seals, the set reduces the risk of leaks and helps sustain pump efficiency and consistent water flow. The rings are sized specifically for the intended filter models to ensure a correct fit and straightforward installation.

Application: Sealing filter housings, pump assemblies, and removable connections

How to use
Turn off and unplug the filter and any connected electrical equipment before servicing. Drain water from the filter housing as needed and disassemble the unit according to the filter manufacturer’s instructions. Remove old O-rings and clean the sealing grooves to remove debris and deposits. Fit the replacement O-rings, ensuring they sit evenly in their grooves without twisting. Reassemble the filter, refill with water, and check for leaks during a brief test run. If any leakage is detected, stop the unit, reseat the rings, and repeat the check.
Usage recommendations
Inspect O-rings regularly during scheduled filter maintenance and replace them at the first sign of cracking, flattening, or permanent deformation. Use gentle, non-abrasive cleaners when cleaning grooves and, if needed, apply a thin film of aquarium-safe silicone or lubricant suitable for O-rings to aid installation and extend seal life.
