Step 1: Measure the size of the end cap
This is a crucial step. The filter element is "inserted" into the casing, and if the size is not correct, nothing else will work.
It is necessary to measure the outer diameter of the end cap and the inner diameter of the center interface, which determine how the filter element seals with the manifold.
Step 2: Check the installation form
Check if it is a flat cover/concave cover or an O-ring sealing interface. Incorrect sealing method can cause serious leakage.
Step 3: Measure the total length
Please measure the total length from the top of the metal cover to the bottom of the filter element.
Step 4: Determine the filtering accuracy
Different hydraulic systems require different filtration accuracies. Please check the manufacturer's label or send us your OEM part number for accurate matching.
