Zodiac – Ceramic weight for acid tube – R0741200

The Zodiac R0741200 is a genuine OEM ceramic weight designed to act as a counterweight and retaining nozzle for the acid dosing tube in Zodiac chlorinator and pH control systems. In these systems, the acid tube must remain correctly positioned and submerged within the chemical canister at all times to ensure accurate and consistent dosing. The ceramic weight anchors the tube in place, preventing it from floating or shifting out of position, which could otherwise interrupt the dosing cycle or cause incorrect pH correction.

Ceramic is used as the material of choice for this component because of its outstanding resistance to the highly corrosive nature of pH-reducing acids commonly used in pool water treatment. Unlike metal or standard plastic alternatives, ceramic maintains its integrity over extended periods of chemical exposure without degrading, corroding, or contaminating the dosing fluid. This makes the R0741200 a long-lasting and reliable component within the chemical feed assembly.

Technical characteristics and compatibility

The R0741200 ceramic weight is a purpose-engineered spare part designed to fit the acid tube assembly used in Zodiac eXO iQ pH/PRO, Hydroxinator iQ, and pH Perfect chlorinator systems. It serves a dual function: it weights the tube to ensure it remains correctly positioned at the bottom of the acid canister, and it acts as a retaining nozzle to stabilise the suction point from which acid is drawn into the dosing pump. Without this component functioning correctly, the dosing pump may draw air rather than acid, leading to inaccurate pH correction and potential damage to the pump head over time.

As a genuine Zodiac replacement part, the R0741200 is manufactured to the exact tolerances and chemical resistance standards required by the original equipment. It is sold as a pack of two units, making it straightforward to service multiple systems or retain a spare for future maintenance. Installation requires no specialist tools — the ceramic weight simply fits onto the end of the acid dosing tube within the chemical canister.

Suitability and application

This spare part is intended for pool owners and pool service professionals who maintain or repair Zodiac eXO iQ pH/PRO, Hydroxinator iQ, or pH Perfect pH dosing and chlorination systems. If your acid dosing tube has become damaged, if the weight has cracked or broken due to chemical exposure or handling, or if routine maintenance reveals wear on this component, the R0741200 is the correct genuine replacement. Using an official Zodiac spare part ensures full compatibility with your system and maintains the reliability of your automated pH control. It is suited to both residential and light commercial pool installations where these Zodiac systems are deployed.
