P551670 Donaldson filter element

9980007 Oil Filter Paper Core Cross Reference P551670 The 9980007 oil filter paper core, cross-referenced with Donaldson P551670, is a high-performance aftermarket lubrication filter element built for heavy-duty commercial vehicles and construction machinery diesel engines. Constructed with multi-layer deep-pleated composite filter media, this paper core effectively traps metal wear debris, carbon sludge, oxidation precipitates and micro abrasive particles suspended in engine lubricating oil. It maintains consistent, smooth oil flow under long-hour high-temperature, high-pressure and heavy-load operating environments, minimizing friction and abrasion on crankshafts, bearings, cylinder liners and other core engine components, stabilizing engine power output and reducing excessive fuel consumption. Manufactured strictly to original OEM dimension standards and verified via IATF16949 filtration performance tests, this dual-part filter core provides long-term stable engine protection for logistics fleets and engineering equipment, lowering engine failure rates and overall vehicle maintenance costs.  Product Material Description: This 9980007 / P551670 filter paper core uses high-density composite cellulose blended with fine glass fiber as the primary filtering medium. The filter paper is processed with high-temperature oil-resistant resin impregnation to avoid fiber shedding, softening and swelling during prolonged contact with hot engine oil. It is equipped with a thick reinforced paper inner support tube to prevent pleat collapse under fluctuating oil pressure, paired with high-elastic NBR nitrile rubber sealing gaskets that feature excellent anti-aging and oil corrosion resistance. All raw materials comply with international heavy-duty vehicle filtration standards, with uniform fiber distribution, balanced oil permeability and outstanding dirt holding capacity.
