Zodiac – Inner shroud pH – R0743300

The Zodiac R0743300 is a genuine replacement inner shroud designed specifically for the pH section of the Zodiac TRi pH and TRi PRO salt water chlorinator systems. This protective inner cover fits directly over the pH electronic board, shielding the sensitive circuitry from moisture, chemical exposure, and physical contact. As a manufacturer-approved spare part, it ensures a precise fit and maintains the integrity of the original equipment design.

The inner shroud plays an important protective role within the Zodiac TRi pH unit. Without this cover properly in place, the pH electronic board is left exposed to the humid and chemically aggressive environment found inside pool equipment enclosures. By keeping this component in good condition, you help extend the service life of the pH control board and maintain reliable automated pH management in your pool system.

Technical characteristics and compatibility

This inner shroud is manufactured to Zodiac’s original specifications, ensuring correct dimensions and fitment for the TRi pH and TRi PRO chlorinator platforms. It is constructed from durable polymer materials suited to the wet and chemically active environment of pool equipment. The part number R0743300 is referenced across Zodiac’s official catalogues from 2018 through to 2023, confirming its continued relevance and availability as a current spare part. Installation requires no specialist tools — the shroud clips or fits into position within the chlorinator housing, making it a straightforward DIY replacement for pool owners and technicians alike.

Suitability and application

This inner shroud is intended exclusively for use with Zodiac TRi pH and TRi PRO salt water chlorinator units. It is not a universal component and should only be used to replace the equivalent part in these specific models. If your existing inner shroud is cracked, warped, or missing, replacing it promptly is recommended to protect the pH electronic board from damage and to keep your chlorination and pH dosing system operating correctly. This part is suitable for both residential and light commercial pool installations where Zodiac TRi pH or TRi PRO chlorinators are deployed.
