Frequently asked questions
Is this a genuine Hydac 1250123?
No. It is an aftermarket hydraulic filter element made to replace the Hydac 1250123. It is not made by or affiliated with Hydac, and the part number is used only to show what it replaces.
Will it fit my machine?
It replaces the element numbered Hydac 1250123 and the other numbers in the cross reference table. Check the number on the old element or in the machine's parts list, or measure it: this one is 51.5 mm (2.03 in) across, 24 mm inside and 101 mm (3.98 in) high.
When should I change the element?
Change the element when the clogging indicator shows it is loaded, or at the hours in the machine's service plan, whichever comes first.
How do I fit it?
Stop the machine and let the pressure out of the circuit. Open the filter housing, take out the old element and clean the bowl. Fit the new element with its new O rings lightly oiled, close the housing to the maker's torque, then run the machine and check for leaks.
