Filter head gasket for Fil 130 / Fil 130 + UV by sera (replacement seal, model SE-30637)

Replacement head gasket designed for sera Fil 130 and Fil 130 + UV canister filters. This sealing ring fits between the filter head and the canister body to establish a watertight connection, preventing leaks and preserving correct suction and flow. The gasket is intended as a direct replacement for worn or damaged seals during routine maintenance, repairs or refurbishment of Fil 130 series units used in home and public aquaria.

Advantages

The gasket provides a reliable seal that restores proper pressure and prevents water escape at the head–canister interface. Made to match the original part geometry, it simplifies installation and reduces the risk of misalignment. Using a dedicated replacement seal helps maintain pump performance and extends the service life of the canister by avoiding leaks that can cause motor or electrical damage.

Suitable for

• Routine maintenance of sera Fil 130 and Fil 130 + UV canister filters
• Repair or refurbishment of used Fil 130 series units
• Service kits assembled by aquarists and professional aquarium technicians
• Home aquaria and public/office aquarium filter upkeep

Key specifications

• Function: head-to-canister sealing gasket for canister filters
• Compatibility: designed for Fil 130 and Fil 130 + UV filter heads
• Material properties: flexible sealing material for water-tight contact
• Purpose: prevents leaks and maintains suction/flow integrity

How to use

Turn off and unplug the filter before disassembly. Separate the filter head from the canister according to the filter's maintenance instructions, remove the old gasket, and clean the sealing surfaces of any debris or residue. Position the replacement gasket evenly in the head or on the canister rim, reassemble the head onto the canister, and ensure the locking clips or clamps are securely fastened. After reassembly, prime the unit and run it briefly to check for leaks and correct suction.

Usage recommendations

Inspect the gasket during regular service intervals and replace it at the first sign of hardening, cracking, compression set or persistent leakage. Use only clean hands or non-abrasive tools when fitting the seal and avoid stretching or twisting the gasket to preserve its sealing function.
