SDLG Hydraulic Filter Element 4120001954001

This is a genuine, high-precision hydraulic pilot filter element (often cataloged as a hydraulic oil filter insert) manufactured for SDLG (Shandong Lingong Construction Machinery) wheel loaders.

This particular filter protects the highly sensitive pilot control hydraulic circuit, ensuring that clean, contaminant-free oil is delivered to the pilot joystick valves and hydraulic control lines.

Key Information

It filters the low-pressure, high-precision oil supply line that responds when an operator moves the cabin joysticks. If tiny metal or silica particulates scratch a pilot valve spool, the joystick can stick or cause jerky, unpredictable boom and bucket actions.

Operating on the PLFX-30x10 profile, it traps microscopic wear debris down to 10 microns, standing as the primary safeguard for downstream pressure-reducing valves.
