Zodiac – AquaPure Ei series sensor pod cap – R0785400

The Zodiac R0785400 is a genuine OEM replacement sensor pod cap designed specifically for the Jandy AquaPure Ei series saltwater chlorination systems. The sensor pod cap serves as the protective housing cover for the salt sensor pod assembly, sealing the sensor components and maintaining the integrity of the chlorinator’s salt detection and measurement system. Without a properly functioning and undamaged pod cap, the sensor assembly is exposed to pool water pressure and debris, which can compromise accurate salt level readings and overall system performance.

The AquaPure Ei series is a popular and widely installed inline saltwater chlorinator range from Zodiac Jandy, used in residential pools. The sensor pod is a critical component of this system, and the cap is the element most likely to crack, warp, or develop leaks over time due to constant water pressure cycling and UV exposure. Using a genuine Zodiac replacement cap ensures the correct thread fit, material compatibility, and watertight seal that third-party alternatives may not consistently provide.

Technical characteristics and compatibility

The R0785400 cap is manufactured to factory specifications and is designed to thread directly onto the sensor pod housing in the AquaPure Ei series chlorinator cell assembly. It is constructed from a durable polymer material suited to prolonged contact with chlorinated and salinated pool water. The cap protects the internal sensor from direct water flow while allowing the sensor to accurately measure the salt concentration in the pool water passing through the system.

This part is sold as an individual unit and is a direct drop-in replacement requiring no tools or modifications beyond standard hand tightening. It is important to verify compatibility with your specific AquaPure Ei model before ordering, as Zodiac produces multiple AquaPure product lines and not all caps are interchangeable between series.

Suitability and application

The R0785400 sensor pod cap is intended exclusively for use with Zodiac Jandy AquaPure Ei series saltwater chlorination systems installed in residential pools. It is the appropriate replacement when the original cap shows signs of cracking, leaking, stripped threads, or physical damage. This is a maintenance spare part suited to pool owners and pool service technicians performing routine upkeep or reactive repairs on the AquaPure Ei chlorinator. If your system is showing salt sensor errors or you notice moisture or leaks around the sensor pod area, inspecting and replacing this cap is a recommended first diagnostic step.
