LF3720 heavy duty truck oil filter insert

9980006 Oil Filter Paper Core Cross Reference JX0814 LF3720 9980006 oil filter paper core with cross part numbers JX0814 and LF3720 is a professional lubrication filter insert designed for medium and heavy commercial diesel engines. Adopting multi-layer deep pleated composite filter media, this paper core efficiently intercepts metal wear debris, carbon sludge, oil oxidation sediment and tiny abrasive impurities mixed in engine oil. It keeps stable and smooth oil circulation under long-term high-temperature, high-pressure and heavy-load working conditions, effectively reducing friction and wear of crankshaft, bearing bushes, cylinder liners and other key engine components, stabilizing engine power output and cutting extra fuel consumption. Manufactured strictly according to original OEM dimensional standards and passing IATF16949 full performance tests, this triple-number filter core offers long-term reliable engine protection for logistics fleets and construction machinery, greatly lowering engine failure frequency and long-term vehicle maintenance costs.  Product Material Description: This 9980006 / JX0814 / LF3720 filter paper core takes high-density composite cellulose mixed with fine glass fiber as main filtering medium. The filter paper is treated with high-temperature oil-resistant resin impregnation, which prevents fiber shedding, softening and swelling after long-time contact with hot engine oil. It is equipped with thick reinforced paper inner support tube to avoid pleat collapse under variable oil pressure, matched with high elastic NBR nitrile rubber sealing gasket with outstanding anti-aging and oil corrosion resistance. All raw materials meet heavy-duty automotive filtration standards, featuring uniform fiber distribution, balanced oil permeability and large dirt holding capacity.
