Weichai diesel engine spare filter

13055724 Heavy Duty Spin-On Diesel Fuel Filter The 13055724 spin-on fuel filter is a premium aftermarket replacement component manufactured strictly to OEM standards for Weichai medium and heavy-duty diesel truck engines, also widely used on passenger coaches, engineering machinery and stationary diesel generator units. During long-distance haulage and continuous heavy-load operation, diesel fuel will inevitably contain rust sediment, metal wear debris, sludge, fine dust and tiny impurities generated during fuel storage and refueling. These contaminants entering the fuel system will scratch fuel pumps, block precision fuel injectors, cause rough idling, difficult cold starting, insufficient acceleration power and higher fuel consumption. This filter adopts multi-layer gradient composite pleated filter media to achieve high-efficiency particle filtration, delivering consistently clean diesel to the engine fuel injection system. It effectively protects core fuel system parts, stabilizes engine power output under harsh working conditions, reduces unexpected breakdown frequency and long-term maintenance costs. Produced under strict automotive quality control standards, it maintains stable filtration efficiency under high fuel pressure and wide temperature changes, serving as an essential reliable maintenance spare part for logistics fleets, vehicle repair shops and construction equipment teams.  Product Material Description: Filter Media: High-density multi-layer composite fiber filter paper with uniform pore size, outstanding filtration precision and large dirt holding capacity; Outer Shell: Thickened high-strength cold rolled steel housing with full electrophoretic anti-rust coating, resistant to diesel corrosion, physical impact and outdoor abrasion; Sealing Gasket: High-grade nitrile rubber (NBR), featuring excellent oil resistance, high & low temperature resistance and long anti-aging performance to realize full leak-proof sealing; Internal Reinforced Galvanized Metal Skeleton: Firmly supports the filter element to prevent deformation or collapse under sustained high working fuel pressure; Precision Standard Thread Interface: 1:1 consistent with original OEM thread size for perfect matching with the original mounting base.

SGFF82001 612630080087 Heavy Duty Diesel Fuel Water Separator SGFF82001 is fully cross-interchangeable with the OEM part number 612630080087 fuel water separator filter, strictly manufactured to original Weichai engine specifications for heavy-duty commercial vehicles and engineering equipment. In daily long-haul transportation and harsh field working conditions, diesel fuel is prone to mixing with free water, rust sediment, metal wear debris, sludge and fine dust during storage and refueling. These harmful contaminants entering the fuel system will lead to fuel injector clogging, fuel pump wear, hard cold starting, rough engine idling, insufficient acceleration power and increased fuel consumption. Adopting advanced multi-layer gradient filtration technology together with a professional hydrophobic water separation layer, this filter can efficiently trap solid impurities and separate moisture from diesel fuel, delivering consistently clean fuel to the engine injection system. It provides comprehensive protection for precision fuel system components, stabilizes engine power output during long-term full-load operation, reduces unexpected equipment downtime and high repair costs. Produced under strict ISO automotive quality standards, it maintains stable filtration efficiency under high fuel pressure and extreme temperature changes, serving as a reliable and cost-effective aftermarket maintenance spare part for logistics fleets, vehicle repair garages and construction machinery teams around the world.  Product Material Description: Filter Medium: High-density multi-layer composite glass fiber filter paper with uniform pore distribution, featuring stable filtration precision and outstanding dirt holding capacity; Outer Shell: Thickened high-strength cold-rolled steel housing with electrophoretic anti-rust coating, resistant to diesel corrosion, external impact and outdoor surface abrasion; Sealing Gasket: Premium nitrile rubber (NBR), with excellent oil resistance, wide high-low temperature resistance and long anti-aging performance to achieve complete leak-proof sealing; Internal Reinforced Galvanized Metal Skeleton: Firmly supports the filter element to prevent deformation or collapse under sustained high working fuel pressure; Hydrophobic Polymer Membrane: Specially formulated water-repellent material to realize highly efficient separation of water and diesel oil.
