O-Ring Seal for Hayward CLX110K Chlorinator Lid – Compatible with CL100/CL110

Affected individuals: Pool owners using the Hayward CL100 or CL110 automatic chlorine tablet dispenser.

Main scenario: Replace the aging O-ring on the electrolyzer cap. A saltwater or chlorine gas environment can easily cause the sealing ring to harden and fail, resulting in chlorine gas leakage or saltwater infiltration. Regular replacement ensures the equipment is properly sealed and prevents corrosion and loss of efficiency.
