O-ring seal for Flore CO2 500/1000 by sera — replacement gasket for CO2 system

Replacement O-ring seal specifically made for the sera Flore CO2 500 and Flore CO2 1000 systems. This gasket is designed to restore and maintain a reliable seal in CO2 regulator and reactor connections compatible with the Flore CO2 500/1000 series, helping preserve system pressure and reduce the risk of leaks during aquarium CO2 dosing.

Advantages

The O-ring is manufactured to fit the mating components of the Flore CO2 500/1000 family, ensuring consistent contact and compression for a tight seal. Its material resists the typical conditions in CO2 systems, providing stable performance during routine operation and maintenance. Using a correctly sized replacement gasket preserves regulator accuracy and minimizes maintenance downtime.

Suitable for

• Replacing worn or damaged seals in sera Flore CO2 500 and 1000 regulators and reactors
• Routine maintenance to prevent CO2 leaks and pressure loss
• Home and professional aquarium CO2 dosing systems compatible with Flore CO2 500/1000 connections

Key specifications

• Function: sealing gasket for CO2 system connections
• Compatibility: designed for use with Flore CO2 500 and Flore CO2 1000 series
• Material properties: elastomeric O-ring suitable for gas sealing and repeated compression
• Intended environment: aquarium CO2 regulators and reactors

How to use

Turn off CO2 flow and relieve system pressure before attempting replacement. Remove the old O-ring from the connection point, clean contact surfaces to remove residue or deposits, and inspect mating parts for wear. Fit the replacement O-ring into the correct groove, ensuring it sits evenly without twists. Reassemble the connection and slowly restore CO2 flow while checking for leaks at the joint; tighten fittings as needed to achieve a secure seal.

Usage recommendations

For reliable performance, replace the O-ring if signs of cracking, flattening, or persistent leakage appear. Store spare gaskets away from direct sunlight and chemical exposure to preserve elasticity. When servicing, use compatible tools and follow manufacturer guidance for the Flore CO2 500/1000 series to avoid damaging threads or sealing surfaces.
