Heavy-Duty Construction Sites
In dusty construction environments, the 25 µm impregnated paper media captures fine particles that can cause wear in hydraulic components. This filter helps extend the life of pumps and valves on excavators and loaders from Caterpillar and Komatsu.
Continuous-Duty Industrial Operations
For machinery running long shifts, the robust construction of this filter ensures consistent filtration without bypass. It maintains oil cleanliness in hydraulic power units, reducing unplanned downtime.
Fleet Maintenance Simplification
With cross-references to over 20 brands, this filter allows fleet managers to stock a single part number for multiple equipment types. It simplifies inventory management for mixed fleets containing Caterpillar and Komatsu machines.
Remote or Harsh Operating Conditions
In mining or agricultural applications where filter changes are infrequent, the 25 µm rating provides adequate protection without excessive restriction. This filter supports reliable operation in extreme temperatures and high-contaminant loads.
Check your original filter's part number against the cross-reference list (Asas, Baldwin, Caterpillar, etc.). Also verify dimensions: height 234 mm, outer diameter 102 mm, inner diameters 59 mm and 50 mm, and Out-In flow direction.
This filter uses impregnated paper media with a 25 µm filtration rating. It is designed for hydraulic systems requiring moderate particle removal efficiency.
The filter has Out-In flow direction. The largest inner diameter is 59 mm and the smallest is 50 mm. For thread specifics, consult your equipment manual or compare with your existing filter.
This is an aftermarket replacement built to the original dimensions and ratings. It is not a genuine OEM part but is designed to directly replace filters from brands like Caterpillar, Donaldson, and Fleetguard.
Installation is similar to the original filter. Ensure the O-ring is lubricated, screw on until the gasket contacts the mounting surface, then tighten an additional 3/4 turn. Do not overtighten.
