998001CX Oil Filter Paper Core Cross Reference P559000 998001CX lubrication filter paper core cross-referenced with Donaldson P559000 is a high-capacity heavy-duty filter insert designed for large-displacement commercial diesel engines. Constructed with multi-layer deep-pleated composite filter media, this paper core efficiently traps metal wear debris, carbon sludge, oil oxidation precipitates and micro abrasive particles suspended in engine lubricating oil. It maintains stable and unobstructed oil circulation under long-hour high-temperature, high-pressure and heavy-load operating environments, effectively reducing friction loss of crankshaft, bearing bushes, cylinder liners and other core engine components, stabilizing engine power output and lowering abnormal fuel consumption. Manufactured strictly to original OEM dimensional standards and fully verified via IATF16949 filtration performance tests, this dual cross-reference filter core provides long-term all-round engine protection for logistics fleets and mining machinery, cutting engine failure rates and overall vehicle maintenance expenses.
Product Material Description:
This 998001CX / P559000 filter paper core adopts high-density composite cellulose blended with ultra-fine glass fiber as the primary filtering medium. The filter paper undergoes professional high-temperature oil-resistant resin impregnation treatment to prevent fiber shedding, softening and swelling after long-term contact with hot engine oil. It is equipped with a thick rigid reinforced paper inner support tube to avoid pleat collapse under fluctuating oil pressure, matched with high-elastic NBR nitrile rubber sealing gasket featuring outstanding anti-aging and oil corrosion resistance. All raw materials comply with international heavy-duty automotive filtration standards, with uniform fiber distribution, balanced oil permeability and super large dirt holding capacity.
