SPEEDAIRE 56602 Mechanical Service Indicator

The SPEEDAIRE 56602 is a mechanical service indicator assembly designed for hydraulic system maintenance. It provides a visual indication of filter element condition to help operators schedule timely replacements. This component is built for integration with compatible hydraulic filter housings. It supports preventive maintenance routines in industrial and mobile machinery applications.

Maintenance Teams Monitoring Filter Life

This assembly suits technicians who need a direct-reading mechanical gauge to track filter restriction without electrical wiring. It is not intended for users requiring electronic sensor outputs or data logging capabilities. Buyers needing a different thread pattern or pressure range should verify compatibility before purchase. The mechanical design offers simplicity for harsh environment reliability.

Compatibility With Listed Grainger Filter Housings

The critical specification is confirmed fitment with Grainger item numbers 4ZL18 through 4ZL55 as detailed in the supplier data. Correct matching ensures proper sealing and accurate restriction readings for the specific filter series. Always cross-reference the housing part number against the approved list before installation. Mismatched components can bypass filtration or leak under pressure.

Questions about this item

Which Grainger filter housings does the Speedaire 56602 indicator thread into?

The mechanical indicator fits Grainger items 4ZL18 through 4ZL26, 4ZL31 through 4ZL36, 4ZL43 through 4ZL46 and 4ZL53 through 4ZL55.

Can the indicator stay on a legacy Speedaire housing when I upgrade the filter element?

Yes, the assembly mounts to the existing Speedaire housing and works with new elements as long as the housing is one of the listed Grainger numbers.

How do I confirm the 56602 is signalling correctly after installation?

Pressurise the system; the mechanical pointer should move into the red zone at the filter's rated differential pressure and return to green when the element is changed.
