998500CX Oil Filter Paper Core Cross Reference LF17500CX 998500CX lubrication filter paper core cross-referenced with LF17500CX is a high-flow heavy-duty oil filter insert specially upgraded for National VI emission standard large-displacement diesel engines. Adopting multi-layer deep-pleated composite high-capacity filter media, this oil filter efficiently traps metal wear debris, carbon sludge, oil oxidation precipitates and micro abrasive particles suspended in high-temperature engine oil. It maintains stable, unobstructed oil circulation under long-hour high-temperature, high-pressure and heavy-load transportation and mining working conditions, significantly reducing friction loss of crankshaft, bearing bushes, cylinder liners and other core engine components, stabilizing engine power output and cutting abnormal fuel consumption. Manufactured strictly according to original OEM dimensional standards and fully passed IATF16949 complete filtration performance tests, this dual cross-reference filter core provides long-lasting full engine protection for large logistics fleets and construction machinery, effectively lowering engine failure rates and long-term vehicle maintenance costs.
Product Material Description:
This 998500CX / LF17500CX filter paper core uses high-density composite cellulose blended with ultra-fine glass fiber as primary filtering medium. The filter paper undergoes professional high-temperature oil-resistant resin impregnation treatment to prevent fiber shedding, softening and swelling after long-time contact with hot lubricating oil. A thick rigid reinforced paper inner support tube is equipped to avoid pleat collapse under fluctuating oil pressure, matched with high-elastic NBR nitrile rubber sealing gasket with outstanding anti-aging and oil corrosion resistance. All raw materials comply with international heavy-duty automotive filtration standards, featuring uniform fiber distribution, balanced oil permeability and super large dirt holding capacity.
