Pool Filter Pressure Gauge
Replacement pressure gauge for monitoring operating pressure on compatible Illuminex pool filters.
Confirm your filter model and gauge connection before ordering.

0–60 PSI Pressure Gauge
Replacement gauge designed to display operating pressure on compatible pool filter assemblies.
0–60 PSI Range
Provides a clear pressure reading across a 0–60 PSI measurement range.
Filter Monitoring
Provides a visual pressure reading during normal filter operation.
Service Replacement
Replacement component for compatible Illuminex filter assemblies.
See What's Happening Inside Your Filter System
The pressure gauge provides a visual reading of the pressure inside the compatible filter system during operation.
Monitoring filter pressure can help the user understand changes in system pressure and determine when the filter should be inspected or serviced according to the current filter manual.
This Gauge Measures Pressure — It Does Not Regulate It
Gauge Measurement Range
Gauge Measurement Range
Measurement range only — not the filter's allowable working-pressure range. The gauge scale indicates measurement range only. Always follow the maximum working-pressure rating and service instructions specified for your filter model.
Compatible Illuminex Filters
This gauge is categorized as a replacement component for the filter families shown below. Specific model compatibility must be confirmed before ordering.
AquaClear Cartridge Filters
Categorized as a replacement part for the AquaClear cartridge-filter family. Specific model compatibility (e.g. LU-CF200, LU-CF425, LU-CF525) must be confirmed from the approved filter parts diagram before ordering.
AquaCrystal Sand Filters
Categorized as a replacement part for the AquaCrystal sand-filter family. Specific model compatibility must be confirmed from the approved filter parts diagram before ordering.
Pressure gauges may use different connection sizes and mounting arrangements. Confirm your filter model and replacement-part information before ordering. A 0–60 PSI gauge does not automatically fit another filter just because that filter operates below 60 PSI.
Where It Fits
Conceptual location of the pressure gauge on a compatible top-mounted filter assembly.
Conceptual product-location visual — refer to the current filter manual and parts diagram for exact installation location.
Pressure Gauge vs. Air-Relief Valve
Some filter assemblies contain both a pressure gauge and a separate manual air-relief component. The pressure gauge is not the air-relief valve. Do not use the gauge opening to release filter pressure — follow the filter manual's approved pressure-relief procedure.
Understanding Your Filter Pressure
Establish Normal Pressure
Refer to the filter manual and note the pressure reading when the system is clean and operating normally.
Watch for Changes
A change from the normal operating pressure may indicate that the filtration system should be inspected.
Follow the Filter Manual
Cleaning, service and pressure limits depend on the specific filter and pool system.
Specific cleaning or backwash pressure thresholds come from your filter manual — this page does not publish arbitrary pressure values.
Gauge Details
Only confirmed information is shown. Dial diameter, connection type, thread size, mounting style, material, and accuracy are not published unless verified in the product record.
When Should the Gauge Be Replaced?
Unreadable Display
Inspect the gauge if the dial, lens or markings become difficult to read.
Visible Damage
Check for physical damage around the gauge body or connection.
Incorrect or Unresponsive Reading
If the gauge no longer responds normally, confirm the system condition and service the gauge according to the filter instructions.
Depressurize Before Service
Turn off the circulation pump and fully relieve pressure from the filtration system before removing or replacing the pressure gauge.
Follow the current filter manual for the correct pressure-relief and service procedure.
Never unscrew the pressure gauge while the pump is running.
Never remove the gauge from a pressurized filter.
Never use the gauge opening to release filter pressure.
What's Included
Package contents come from the actual product record. No O-ring, gasket, thread adapter, or hardware is shown unless actually included.
