Donaldson P550425 Premium Oil Filter for Engine Lubrication

Superior engine lubrication protection defines the Donaldson P550425, engineered to trap 99% of 20-micron contaminants—metal particles, sludge, carbon deposits, and abrasive debris—from engine oil. Compatible with commercial trucks, construction machinery, industrial engines, and agricultural equipment, it safeguards critical components like bearings, pistons, and camshafts from wear.

Featuring premium synthetic-blend filter media with 40% higher dirt-holding capacity than standard filters, it boasts a leak-tight seal to prevent unfiltered oil bypass and rugged construction that resists high temperatures and pressure fluctuations. Backed by Donaldson’s filtration expertise, the Donaldson P550425 maintains oil purity, enhances lubrication efficiency, extends engine lifespan, and reduces maintenance costs for reliable long-term performance.
