LF17500 heavy duty lube filter element

998500 Oil Filter Paper Core Cross Reference LF17500 998500 lubrication filter paper core cross-referenced with LF17500 is a high-capacity heavy-duty oil filter insert designed for large-displacement National VI diesel engines. Adopting multi-layer deep-pleated composite filter media, this oil filter efficiently captures metal wear debris, carbon sludge, oil oxidation precipitates and tiny abrasive contaminants suspended in high-temperature engine oil. It maintains stable and unobstructed oil circulation under long-hour high-temperature, high-pressure and heavy-load working conditions, effectively reducing friction and abrasion on crankshaft, bearing bushes, cylinder liners and other core engine components, stabilizing engine power output and cutting abnormal fuel consumption. Manufactured strictly in accordance with original OEM dimensional standards and fully verified by IATF16949 filtration performance tests, this dual cross-reference oil filter delivers long-term comprehensive engine protection for logistics fleets and mining machinery, lowering engine failure rates and overall vehicle maintenance costs.  Product Material Description: This 998500 / LF17500 oil filter paper core adopts 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 prolonged 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 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.
