Description
Internal Cover Gasket to Prevent Water Bypass
The Oase BioSmart 5000–10000 / Biotec 5.1–10.1 inside cover gasket (part 27846) seals the internal cover plate that separates the filter's inlet chamber from its media stages. Without a proper seal, incoming water short-circuits past the foam media and returns to the pond only partially filtered, undermining water clarity and biological performance.
Eliminates Hidden Bypass
Because this gasket sits inside the filter, a failure is invisible from the outside — the only symptom is gradually declining water quality despite clean foam. Replacing the gasket during routine maintenance is cheap insurance against this hidden problem. The OEM rubber compound resists compression set and biological fouling.
| Specification | Details |

| Compatible Models | BioSmart 5000, 7000, 10000; Biotec 5.1, 10.1 |
| Part Number | 27846 |
| Material | Rubber elastomer |

Installation
Power off the pump and open the filter lid. Lift out the foam assemblies to access the internal cover plate. Peel the old gasket from the groove, clean any residue, and seat the new gasket evenly. Reassemble the foam stages in the correct colour order, close the lid, and restart the system.
Ideal for annual spring maintenance on BioSmart and Biotec compact filters, especially when water clarity has dropped for no obvious reason.
