1001120353A oil filter

1001120353A Heavy Duty Engine Oil Filter The 1001120353A oil filter is a precision aftermarket replacement filter specially developed to match Weichai series heavy-duty diesel engines, widely used on medium and heavy logistics trucks, dump trucks, passenger coaches and engineering vehicles. During long-distance haulage and continuous heavy-load operation, engine lubricating oil will inevitably mix with metal wear debris, carbon deposits, sludge, dust and tiny impurities generated inside engine operation. If these contaminants circulate in the lubrication system, they will cause severe abrasion to crankshafts, bearings, pistons and other precision core components, resulting in unstable oil pressure, engine noise, insufficient power, rising fuel consumption and shortened engine service life. Adopting advanced multi-layer gradient filtration technology, this 1001120353A filter efficiently traps fine solid pollutants to keep engine oil clean and smooth circulation of lubricant. It effectively reduces internal engine wear, lowers unexpected breakdown rates and daily maintenance costs. Produced strictly in line with automotive heavy-duty industrial standards, it maintains stable filtration performance under high oil pressure and high-temperature working environments, acting as a reliable safeguard for long-running fleets and engineering equipment working in complicated road and weather conditions.  Product Material Description: Filter Medium: High-density multi-layer composite fiber filter paper with compact pleated structure, stable filtration precision, large dirt holding capacity and excellent compatibility with all conventional diesel engine lubricating oil; Outer Housing: Thickened high-strength cold rolled steel shell with full electrophoretic anti-rust coating, resistant to engine oil corrosion, external impact and outdoor scratch damage; Sealing Gasket: High-performance nitrile rubber (NBR), featuring outstanding high temperature resistance, oil resistance and anti-aging properties, realizing complete tight sealing without oil leakage under long-term compression; Internal Reinforced Galvanized Metal Skeleton: Effectively supports the filter element to prevent deformation or collapse under long-time high lubrication pressure; Built-in Silicone Anti-Drain Back Valve: Prevents oil backflow after engine shutdown perfectly, avoiding dry startup wear on critical engine parts.
