FS19925 Fuel Water Separator Filter Paper Core FS19925 filter paper core is a professional fuel water separation filter element manufactured to match Fleetguard OEM standards, designed for heavy-duty commercial vehicles and construction machinery equipped with Cummins diesel engines. This composite pleated filter medium combines fine impurity interception and efficient water removal performance. It can effectively trap metal rust, sediment, carbon particles and other solid contaminants mixed in diesel, while isolating free water inside fuel. Stable fuel delivery is guaranteed under long-hour heavy-load operation, which prevents fuel injector clogging, fuel pump corrosion and engine power loss. Made with precise original size specifications and full performance testing, this filter core serves as a reliable daily maintenance spare part, effectively protecting the whole fuel system and lowering long-term vehicle failure and maintenance costs for logistics fleets and engineering equipment owners.
Product Material Description:
The FS19925 paper core adopts high-density composite cellulose mixed with ultra-fine glass fiber as the main filtration material. The filter paper is treated with hydrophobic and diesel-resistant resin impregnation, which avoids fiber shedding, swelling and hydrolysis after long-time contact with diesel fuel. A thick rigid reinforced inner support tube is added to prevent pleat collapse under fuel pressure fluctuation. The matched sealing gasket is high elasticity NBR nitrile rubber, with strong resistance to oil corrosion, aging and temperature changes. All raw materials comply with IATF16949 auto filtration standards, featuring uniform fiber distribution, smooth fuel flow and large dirt-water storage capacity.
