9980013 Oil Filter Paper Core Cross Reference K49C1-1012240K2 9980013 lubrication filter paper core cross-referenced with OEM number K49C1-1012240K2 is a dedicated high-efficiency filter insert developed for heavy-duty commercial vehicles equipped with Yuchai diesel engines. Constructed with multi-layer deep-pleated composite filter media, this paper core effectively traps metal wear debris, carbon sludge, oil oxidation precipitates and micro abrasive contaminants suspended in high-temperature engine oil. It maintains smooth, stable oil circulation under long-distance heavy-load transportation and harsh high-temperature working conditions, significantly reducing friction and abrasion on crankshaft, bearing bushes, cylinder liners and other vital engine components, stabilizing engine power performance and lowering abnormal fuel consumption. Manufactured strictly according to original OEM dimensional standards and fully verified by IATF16949 filtration performance tests, this dual-part filter core provides long-lasting comprehensive engine protection for logistics fleets and construction machinery, effectively cutting engine failure rates and overall vehicle maintenance costs.
Product Material Description:
This 9980013 / K49C1-1012240K2 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 prolonged contact with hot lubricating oil. It is equipped with a thick rigid reinforced paper inner support tube to avoid pleat collapse under fluctuating oil pressure, paired with high-elastic NBR nitrile rubber sealing gasket with outstanding anti-aging and oil corrosion resistance. All raw materials comply with heavy-duty automotive filtration standards, featuring uniform fiber distribution, balanced oil permeability and large dirt holding capacity.
