P164166 Donaldson Hydraulic Filter High-performance hydraulic system protection is the core of the Donaldson P164166, engineered to trap 99% of 15-micron contaminants—metal particles, sludge, abrasive debris, and varnish—from hydraulic fluid. Compatible with construction machinery, industrial hydraulic systems, agricultural equipment, and mobile hydraulics, it safeguards critical components like pumps, valves, cylinders, and hoses from premature wear.

Featuring advanced high-efficiency filter media with 38% higher dirt-holding capacity than standard filters, it boasts a leak-tight seal to prevent unfiltered fluid bypass and robust construction that resists extreme pressures (up to 5000 psi) and temperature fluctuations (-40℃ to 120℃). Backed by Donaldson’s filtration expertise, it maintains fluid cleanliness, ensures smooth system operation, extends component lifespan, and reduces maintenance downtime and costs for reliable heavy-duty performance.
