heavy duty truck lubrication filter insert

998001CX Oil Filter Paper Core Cross Reference P559000 998001CX lubrication filter paper core cross-referenced with Donaldson P559000 is a high-capacity heavy-duty filter insert designed for large-displacement commercial diesel engines. Constructed with multi-layer deep-pleated composite filter media, this paper core efficiently traps metal wear debris, carbon sludge, oil oxidation precipitates 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 environments, 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 to original OEM dimensional standards and fully verified via IATF16949 filtration performance tests, this dual cross-reference filter core provides long-term all-round engine protection for logistics fleets and mining machinery, cutting engine failure rates and overall vehicle maintenance expenses.  Product Material Description: This 998001CX / P559000 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 long-term contact with hot engine oil. It is equipped with a 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.

9980007 Oil Filter Paper Core Cross Reference P551670 The 9980007 oil filter paper core, cross-referenced with Donaldson P551670, is a high-performance aftermarket lubrication filter element built for heavy-duty commercial vehicles and construction machinery diesel engines. Constructed with multi-layer deep-pleated composite filter media, this paper core effectively traps metal wear debris, carbon sludge, oxidation precipitates and micro abrasive particles suspended in engine lubricating oil. It maintains consistent, smooth oil flow under long-hour high-temperature, high-pressure and heavy-load operating environments, minimizing friction and abrasion on crankshafts, bearings, cylinder liners and other core engine components, stabilizing engine power output and reducing excessive fuel consumption. Manufactured strictly to original OEM dimension standards and verified via IATF16949 filtration performance tests, this dual-part filter core provides long-term stable engine protection for logistics fleets and engineering equipment, lowering engine failure rates and overall vehicle maintenance costs.  Product Material Description: This 9980007 / P551670 filter paper core uses high-density composite cellulose blended with fine glass fiber as the primary filtering medium. The filter paper is processed with high-temperature oil-resistant resin impregnation to avoid fiber shedding, softening and swelling during prolonged contact with hot engine oil. It is equipped with a thick reinforced paper inner support tube to prevent pleat collapse under fluctuating oil pressure, paired with high-elastic NBR nitrile rubber sealing gaskets that feature excellent anti-aging and oil corrosion resistance. All raw materials comply with international heavy-duty vehicle filtration standards, with uniform fiber distribution, balanced oil permeability and outstanding dirt holding capacity.

9980004 Oil Filter Paper Core With Nut LF16352 9980004 filter paper core matched with LF16352 is a built-in nut type oil filter element designed for mainstream heavy-duty diesel engines. Equipped with an integrated metal mounting nut, this pleated composite filter paper core can be quickly installed and disassembled without extra tools. It efficiently captures metal wear particles, carbon sludge, oil oxidation residues and tiny impurities circulating in lubricating oil. Under high temperature, high pressure and long-term heavy-load driving conditions, it maintains smooth and stable oil circulation, effectively reducing abrasion of engine crankshaft, bearings and cylinder components, stabilizing engine power and lowering fuel consumption. Manufactured strictly in accordance with OEM size standards, this filter core passes complete filtration performance tests, bringing convenient maintenance experience for logistics fleets, engineering machinery and heavy trucks, greatly cutting engine failure probability and vehicle maintenance costs.  Product Material Description: This 9980004 LF16352 filter core adopts composite cellulose mixed with fine glass fiber as the main filter medium. The filter paper is treated with high temperature and oil resistant resin impregnation to prevent fiber shedding, swelling and damage after long-term contact with hot engine oil. It comes with an integrated corrosion-resistant metal nut for fast installation, thick reinforced paper support tube to avoid pleat collapse under fluctuating oil pressure, and high elasticity NBR nitrile rubber sealing gasket. All raw materials meet IATF16949 automotive filtration standards, featuring uniform fiber distribution, good oil permeability and strong dirt holding capacity.
