## Summary description

Replacement seal (gasket) designed for Tetra external filter heads EX500, EX700 and EX1000 Plus. OEM part T304659 ensures proper sealing of the filter head to prevent leaks and maintain correct water flow. Suitable for maintenance and repair of compatible Tetra external aquarium filters to restore reliable operation and extend equipment life.

## Long description

Replacement seal gasket designed for use with Tetra external filter heads EX500, EX700 and EX1000 Plus. This molded rubber gasket fits into the filter head housing to create a watertight connection between the head and the filter canister, preventing leaks and maintaining consistent water flow for effective filtration. The gasket is intended as a maintenance or repair part to restore proper sealing and extend the service life of compatible Tetra external aquarium filters.
Advantages
The gasket provides reliable sealing performance that helps avoid water leaks and pressure loss in external filter systems. Made from resilient elastomer material, it resists deformation under compression and maintains elasticity over repeated assembly and disassembly. Using a correct, purpose-made replacement gasket preserves original filter performance and reduces the risk of premature wear to other sealing surfaces.
Suitable for
Repairing Tetra external filter heads EX500, EX700 and EX1000 Plus
Routine maintenance to replace aged or damaged seals
Preventing leaks after reassembling the filter following cleaning
Key specifications
Function: head-to-canister sealing gasket for external aquarium filter
Material: elastic rubber/elastomer suitable for freshwater aquarium use
Compatibility: designed to fit specific Tetra external filter head models listed above
Form: molded ring gasket sized to match the filter head sealing groove
Operation: maintains watertight seal under typical filter operating pressures
How to use
Turn off the filter and disconnect power before performing any maintenance. Carefully separate the filter head from the canister, drain water as needed and remove the old gasket. Clean the sealing surfaces to remove debris, scale or residue. Fit the replacement gasket into the groove on the filter head, ensuring it sits evenly and is not twisted. Reassemble the head and canister, hand-tighten according to the manufacturer’s guidance, then reconnect and run the filter while checking for any leaks.
Usage recommendations
Inspect the gasket periodically during routine maintenance and replace it if you notice cracks, flattening, or surface damage. Use only compatible replacement parts to ensure proper fit and sealing performance. Avoid using harsh solvents on the gasket and keep spare seals on hand to minimise downtime during repairs.
