Zodiac - Locking ring for AquaPure Ei series - R0768200

Zodiac – Locking ring for AquaPure Ei series – R0768200

The Zodiac R0768200 is a genuine replacement locking ring designed specifically for the Zodiac AquaPure Ei series salt chlorination systems. This black locking collar secures the electrode cell pod firmly in place within the salt chlorinator housing, ensuring a watertight, leak-free connection between the electrode and the system body. Over time, repeated removal of the electrode for cleaning or inspection can wear down the original locking ring, making a reliable replacement essential for maintaining system integrity and optimal chlorination performance.

The locking ring threads onto the AquaPure Ei cell housing and tightens to create a firm mechanical seal. Its robust PVC-compatible construction is designed to withstand continuous exposure to chlorinated, saline pool water without degrading. The black colour and form factor are matched precisely to the original OEM specification, meaning it integrates seamlessly without requiring any modification. It is also listed under the cross-reference part number R0511300, confirming its application across compatible Ei series configurations.

Technical characteristics and compatibility

The R0768200 locking ring is engineered for use with Zodiac AquaPure Ei series salt chlorinators, including the AquaPure Ei25 and Ei35 models. The ring is constructed from durable polymer material capable of withstanding the chemically aggressive environment inside a salt water pool system. Its thread profile is matched to the Ei cell housing, allowing hand-tightening to achieve a secure and leak-proof seal without the need for additional tools or sealants. The compact design ensures the electrode pod is held firmly in alignment, which is important for consistent electrolytic chlorine generation. This part is sold as a direct OEM replacement, meaning it meets the same dimensional and material tolerances as the original factory-fitted component.

Suitability and application

This locking ring is intended exclusively for residential pools equipped with a Zodiac AquaPure Ei series salt chlorination system. It is a maintenance and repair component, most commonly needed when the original ring has cracked, stripped its threads, or no longer creates a reliable seal around the electrode pod. If you are experiencing minor leaks around the electrode housing, or if the existing ring shows visible wear or damage, replacing it with the R0768200 is the recommended corrective action. It is not suitable for other Zodiac product lines outside the Ei series. Pool owners and installers who regularly service AquaPure Ei systems are advised to keep a spare on hand, given how frequently the electrode cell is removed during routine maintenance.
