L131-030-AM JAC truck oil filter

L131-030 Oil Filter Paper Core The L131-030 filter paper core (full model L131-030-AM) is an OEM-grade cartridge-style full-flow engine oil filter inner element, professionally developed to match Yuchai YC4FA, YC4FB series electronic injection diesel engines for JAC light commercial trucks, city buses and sanitation engineering vehicles. Produced strictly in accordance with IATF 16949 international automotive quality standards, this deep-pleated composite filter core adopts imported HV gradient density wood pulp filter paper with glass fiber composite technology. It efficiently traps engine metal wear debris, carbon soot, oil sludge, oxidized colloids and fine solid contaminants suspended in circulating lubricating oil, thoroughly cleaning engine oil before it flows to crankshafts, bearings, camshafts and turbocharger precision moving components. It effectively reduces mechanical abrasive wear, prevents oil passage blockage and premature engine aging, perfectly adapting to frequent start-stop urban delivery operations, bumpy rural road conditions, high-temperature engine compartments and low-temperature cold regional working environments. With precise OEM standardized dimensional molding, it supports direct plug-and-play installation on matched filter housings without modification, acting as an essential daily maintenance consumable for global urban logistics fleets, light truck freight companies, passenger bus operators and vehicle aftermarket repair workshops.  Product Material Description: Main Filter Medium: Premium imported HV composite wood pulp filter paper blended with fine glass fiber, featuring uniform gradient pore structure, excellent dirt holding capacity and stable high-temperature oil resistance for long-cycle light-duty engine filtration work. End Cap Structure: Reinforced rigid black engineering plastic upper and lower end caps with integrated central positioning structure, high structural rigidity to resist deformation and collapse under frequent engine oil pressure fluctuations. Sealing Components: High-quality HNBR hydrogenated nitrile rubber O-ring sealing gasket, with outstanding oil resistance, wide working temperature range (-30℃ ~ 120℃) and long anti-ageing service life to achieve complete leakproof sealing. Bonding Adhesive: High-temperature resistant oil-proof hot melt adhesive, firmly laminates multi-layer filter paper tightly, never dissolves or peels off after long-term immersion in conventional engine lubricating oil.
