LF9035 truck lubrication filter insert

998300 Oil Filter Paper Core Cross Reference LF9035 998300 lubrication filter paper core cross-referenced with LF9035 is a large-capacity heavy-duty filter insert designed for high-power commercial diesel engines. Adopting multi-layer deep-pleated composite filter media, this paper core efficiently captures metal wear debris, carbon sludge, oil oxidation sediment 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 conditions, 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 according to original OEM dimensional standards and fully tested under IATF16949 filtration performance standards, this dual cross-reference filter core provides long-term stable engine protection for large logistics fleets and mining machinery, cutting engine failure rates and overall vehicle maintenance costs.  Product Material Description: This 998300 / LF9035 filter paper core uses high-density composite cellulose blended with ultra-fine glass fiber as the main 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 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.
