## Long description

Replacement head seal designed for the Tetra EX1500 Plus aquarium filter head. This gasket creates a secure, watertight connection between the filter head and canister body to prevent leaks and maintain correct filter operation. It is intended for service and repair of EX1500 Plus units and is suitable when the original seal shows signs of wear, deformation, hardening or is missing.
Advantages

How to use
Turn off and unplug the filter, then detach the filter head from the canister according to the manufacturer's maintenance instructions. Remove the old gasket and clean the sealing surfaces to remove debris and deposits.

Inspect the replacement seal regularly during maintenance intervals and replace it at the first sign of hardening, cracking or permanent deformation. Use only seals compatible with the EX1500 Plus to ensure proper fit and avoid damage to the filter head. Follow all safety and handling instructions for the filter when performing repairs.
