Zodiac – TRi squeeze pump tube 200mm – R0737300

The Zodiac TRi Squeeze Pump Tube is a genuine replacement peristaltic pump tube designed specifically for the Zodiac TRi Series and TRi XO pool chlorinator and pH dosing systems. Measuring 200mm in length, this black silicone-style tube sits inside the peristaltic pump head of the acid dosing unit, where it is repeatedly compressed and released by rollers to move precise volumes of acid from the storage container into the pool water. Because the fluid only ever contacts the inside of the tube and never the pump mechanism itself, the tube acts as both the fluid conduit and the seal — making its condition critical to accurate and safe chemical dosing.

Over time, the repeated mechanical squeezing of the tube causes wear, micro-cracks, and eventual failure, which can lead to inaccurate acid delivery or leaks. Replacing this tube at the first sign of deterioration — or as part of routine preventive maintenance — is essential to keeping the pH balance of your pool water correct and protecting the wider chlorinator system from chemical damage.

Technical characteristics and compatibility

This tube has been produced to OEM Zodiac specifications for the TRi product family. It is 200mm long, which is the correct dimension for the peristaltic pump housing used in Zodiac TRi Series and TRi XO controllers. The tube is black in colour and is engineered to resist the chemical aggressiveness of the acid solutions commonly used in pool pH correction. The part was formerly also referenced under the part number W501211, confirming that R0737300 is the current and direct successor reference for the same component. The tube is supplied without a connection fitting, meaning it is the tube body itself — the section that travels through the pump head — rather than a complete assembly with end connectors.

Installation requires access to the peristaltic pump compartment of the Zodiac TRi or TRi XO unit. The old tube is removed from the pump rollers and end retainers, and the new tube is fitted in its place. No special tools are typically required, though familiarity with the chlorinator’s pump assembly is recommended. Always isolate the dosing system and follow safety precautions when handling acid-handling components.

Suitability and buying context

This replacement tube is intended for pool owners and technicians maintaining a Zodiac TRi Series or TRi XO chlorinator equipped with a peristaltic acid dosing pump. It is not a universal tube and should only be fitted to the specific Zodiac pump models for which it was designed. If your pool uses a Zodiac TRi system for automated pH control and you are experiencing dosing inaccuracies, visible tube wear, or routine annual servicing is due, this is the correct OEM replacement component. It is not suitable for pools using third-party or non-Zodiac dosing systems, and should not be substituted with generic tubing of similar dimensions, as the material specification and dimensional tolerances are matched to the Zodiac pump rollers.
