Zodiac – Top plastic control box bonnet with black sticker Tri Expert – R0743203

The Zodiac R0743203 is the official replacement top plastic bonnet (upper hood) with integrated black sticker for the control box of the Zodiac TRi and TRi Expert salt water chlorinator systems. Over time, the plastic upper cover of a chlorinator control box can become discoloured, cracked, or physically damaged due to prolonged UV exposure and the demanding outdoor pool environment. This genuine Zodiac spare part allows you to restore the control box to its original condition without replacing the entire chlorinator unit, making it a cost-effective and straightforward maintenance solution.

The bonnet serves both a functional and aesthetic role: it protects the internal electronics of the control box from environmental exposure while presenting the clean, finished appearance expected from a Zodiac TRi installation. The black sticker panel is pre-applied or included with the bonnet, replicating the original factory appearance of the TRi Expert control interface.

Compatibility and technical details

This part is specifically designed and validated for use with the Zodiac TRi and Zodiac TRi Expert salt water chlorinator ranges. It is a direct OEM replacement component, meaning it is manufactured to the same specifications as the original part supplied with the chlorinator. The part number R0743203 is the authoritative reference used by Zodiac and its authorised distributors to identify this exact component. Because it is a genuine Zodiac part, fitment is precise and no modification is required during installation. The upper plastic bonnet clips or fastens onto the control box housing in the same manner as the original, ensuring a secure and weatherproof fit.

The material is a UV-resistant engineering plastic, typical of Zodiac chlorinator components designed for permanent outdoor installation in pool environments. The included black sticker provides the correct labelling and visual identity for the TRi Expert control panel fascia.

Suitable application and buying guidance

This replacement part is intended for pool owners and pool technicians maintaining a Zodiac TRi or TRi Expert salt water chlorinator. If the existing top bonnet of your chlorinator control box is cracked, yellowed, broken, or missing, this genuine Zodiac replacement restores the unit’s integrity and appearance. It is not a universal part and should only be fitted to the compatible TRi and TRi Expert models as specified by Zodiac. Always verify your chlorinator model before ordering to ensure compatibility. This is a genuine OEM spare part sourced through official Zodiac distribution channels.
