Zodiac – Next Gen Module rear cover – R0825400

The Zodiac R0825400 is a genuine replacement rear cover designed specifically for the Next Gen Module (TNG Module) used in Zodiac’s eXO iQ pH/PRO and Hydroxinator iQ pH/PRO chlorinator systems. This cover serves as the protective outer casing for the rear of the module, shielding internal electronic and dosing components from environmental exposure, moisture, and physical damage. As an original Zodiac spare part, it is manufactured to the exact tolerances and specifications of the original component, ensuring a precise and secure fit without modification.

This part is intended for pool owners or technicians who need to restore the physical integrity of their chlorinator module housing after damage, wear, or breakage. Using a genuine OEM cover maintains the correct IP-rated enclosure conditions for the electronics inside and preserves the reliability of the overall system.

Technical characteristics and compatibility

The R0825400 rear cover is specifically engineered for the Next Gen Module (TNG) platform used across multiple Zodiac salt chlorinator systems. It is confirmed compatible with the Zodiac eXO iQ pH/PRO and the Hydroxinator iQ pH/PRO product lines. The cover is constructed from durable UV-stabilised plastic suitable for outdoor pool environments, where prolonged sun exposure, humidity, and chemical vapours are common conditions. The component attaches to the rear of the control module housing, completing the sealed enclosure that protects the system’s internal circuitry and pH/ORP sensing connections.

Because this is a genuine Zodiac part supplied under the exact SKU R0825400, customers can be confident in full dimensional compatibility with the original housing assembly. No drilling, trimming, or adaptation is required for correct installation.

Suitability and application

This replacement rear cover is suitable for residential swimming pools running Zodiac eXO iQ or Hydroxinator iQ chlorination systems equipped with the Next Gen Module. It is a maintenance and repair component, not a standalone device. It is typically required when the original rear cover has been cracked, broken, lost, or damaged during servicing. Pool technicians and experienced DIY pool owners can replace this component without specialist tools. This part is not compatible with older Zodiac chlorinator generations that do not use the TNG module platform. Always verify your chlorinator model before ordering to ensure correct fitment.
