Ceramic disc with seal for sera Flore CO2 pressure diffuser (replacement part)

Ceramic disc with seal for sera Flore CO2 pressure diffuser (replacement part) restores the fine-bubble diffusion element of the original sera Flore CO2 pressure diffuser. This replacement set includes the porous ceramic disc and a sealing gasket designed to fit the pressure diffuser housing, allowing consistent CO2 transfer into planted aquariums after the original ceramic component becomes worn, clogged, or damaged. The part is intended for maintenance and repair of the sera Flore CO2 pressure diffuser and helps re-establish stable bubble production and diffusion efficiency.

Advantages

The ceramic disc provides a uniform, fine-bubble output that improves CO2 dissolution and distribution in the water column. The included seal ensures a tight connection between the ceramic element and the diffuser body to prevent gas leakage and maintain operating pressure. Replacing the ceramic disc and gasket is a targeted repair that can extend the service life of the diffuser without replacing the entire unit. The spare part is manufactured to fit the original diffuser geometry for straightforward installation and reliable performance.

Suitable for

• Repairing a sera Flore CO2 pressure diffuser with worn, clogged, or cracked ceramic element
• Routine maintenance to restore fine-bubble CO2 diffusion and improve gas dissolution
• Reducing CO2 loss through leaks by replacing a degraded sealing gasket
• Aquarists managing planted freshwater aquaria who require stable CO2 dosing

Key specifications

• Replacement porous ceramic disc sized to match the sera Flore CO2 pressure diffuser
• Sealing gasket designed for pressure-tight fit within the diffuser assembly
• Materials: sintered ceramic disc and elastomer seal suitable for CO2 exposure
• Function: produces micro-fine bubbles for improved CO2 dissolution
• Intended use: spare part for maintenance and repair of the pressure diffuser

How to use

Switch off and depressurize the CO2 system before disassembling the diffuser. Remove the diffuser from the reactor or tubing, open the diffuser housing according to the manufacturer’s instructions, and extract the old ceramic disc and gasket. Clean the interior of the diffuser housing to remove any residues or algae. Fit the new ceramic disc and place the sealing gasket in the correct position, ensuring alignment with the diffuser seat. Reassemble the housing, reattach the diffuser to the CO2 line, pressurize the system and check for leaks. Allow a short run-in period for the new ceramic element to produce consistent fine bubbles.

Usage recommendations

Perform routine visual checks and gentle cleaning of the diffuser housing to prevent clogging; avoid using aggressive chemicals on the ceramic disc or seal. Replace the ceramic disc and gasket if bubble size increases, output becomes irregular, or leaks are detected. Use with properly regulated CO2 pressure as specified by the sera Flore CO2 system to ensure optimal performance and longevity of the replacement parts.
