P551290 Donaldson Hydraulic Filter High-efficiency hydraulic system protection defines the Donaldson Hydraulic Filter, trapping 99% of 8-micron contaminants—metal particles, sludge, debris, varnish—from hydraulic fluid. Compatible with construction machinery, industrial hydraulics, agricultural and mobile systems, it protects key components (pumps, valves, cylinders, hoses) from premature wear.

Featuring high-grade filter media with strong dirt-holding capacity for longer service, it has a leak-tight seal stopping unfiltered fluid bypass and durable build resisting extreme pressures (up to 5000 psi) and temperatures (-40℃ to 120℃). Backed by Donaldson’s expertise, it maintains fluid cleanliness, ensures smooth operation, extends component life, and cuts maintenance costs for reliable heavy-duty performance.Donaldson P551290
