Zodiac – C-Series chlorinator blank cap – C0322100

The Zodiac C0322100 is a replacement blank cap designed specifically for use with the Zodiac C-Series salt water chlorinator range. This blank cap serves as a sealing plug for the chlorinator cell port or unused connection point, providing a secure, watertight closure when that port is not in active use. By fitting snugly into the designated opening, it prevents water ingress, leakage, and potential contamination of the chlorinator system, helping to maintain the overall integrity and efficiency of the sanitisation unit.

Constructed to the tight tolerances required by Zodiac’s C-Series platform, the blank cap ensures a reliable seal under normal pool operating pressures. Its design allows for straightforward installation and removal without specialist tools, making it a practical component for both installers and pool owners performing routine maintenance or reconfiguration of their chlorination system. The cap is manufactured to Zodiac’s OEM standards, ensuring full compatibility and a proper fit with C-Series chlorinator housings.

Technical characteristics and compatibility

The C0322100 blank cap is an original Zodiac spare part, engineered as a direct replacement for the C-Series chlorinator. Its primary function is to cap off an open port on the chlorinator body, which is essential when a particular inlet or outlet connection is not being used within the pool plumbing layout. This prevents any bypass of water or air that could reduce the effectiveness of the chlorination process or cause unwanted leaks around the unit. The cap is designed to withstand the chemical environment typical of a salt chlorination system, including exposure to saline water and standard pool chemicals. Its compact form factor means it integrates cleanly with the chlorinator housing without adding unnecessary bulk or complexity to the installation.

Suitability and application

This blank cap is intended for use with Zodiac C-Series chlorinators installed in residential or light commercial pool systems. It is particularly relevant when the chlorinator is configured in a way that leaves one or more ports unused, or when an existing cap has been lost, damaged, or has deteriorated over time. As a genuine Zodiac OEM replacement part, it is the recommended option for maintaining the warranty-compliant and manufacturer-approved configuration of your C-Series chlorinator. Pool owners, installers, and service technicians working with Zodiac C-Series units will find this a straightforward, cost-effective solution to ensure the system remains fully sealed and operating at its intended efficiency.
