The Jandy R0452500 Port Sensor Kit is the genuine Zodiac/Jandy 16-foot flow and salinity sensor for AquaPure® 700 and 1400 salt chlorination systems. It ships with the O-ring and fits new-style 3-port cells. When your system reports incorrect salt readings or a no-flow condition, a failed sensor is the usual culprit.

Frequently Asked Questions
What does the Jandy R0452500 sensor do?
It reports flow, salinity, and temperature back to the AquaPure controller — the data the system uses to regulate chlorine production and detect a no-flow condition.
Which cells does it fit?
New-style 3-port AquaPure cells on the 700 and 1400 systems. It's a slotted sensor, not threaded — verify which style your cell uses before ordering.
How do I know the sensor has failed?
Typical symptoms are salt readings that don't match a test kit, a persistent no-flow error while the pump is clearly running, or wildly fluctuating temperature readings.
Does it include the O-ring?
Yes — the O-ring is included and should always be replaced along with the sensor.
How long is the cable?
16 feet, matching the factory run from the cell to the power center.
Is it a genuine Jandy part?
Yes — genuine Zodiac/Jandy OEM. Sensor calibration must match the controller, so OEM matters on this part.
Frequently asked questions
How do I know which O-ring or gasket size I need?
Seals are specified by inside diameter and cross-section thickness, not by the equipment they sit in. Measure the old seal, or use the part number from your equipment's parts diagram, since visually similar rings are frequently a size apart.
What is the part number for this seal?
Jandy lists this seal under part number R0452500. Quote R0452500 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
Should I lubricate the seal on installation?
Yes - a thin film of silicone-based pool lubricant helps the seal seat evenly and makes the next service far easier. Do not use petroleum-based grease, which swells and degrades most elastomers used in pool equipment.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Jandy equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
How often do pool seals need replacing?
Seals are consumables. Replace them whenever the component is opened, and sooner if you see flattening, cracking, a chalky surface or any weeping. A failed seal on the suction side draws air and can make a pump lose prime.
Is there a warranty on this seal?
It carries the standard Jandy manufacturer warranty. The terms are set by Jandy, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
