Fuel filter (water separator with increased efficiency) with part number 3087298 from the REDX offer. It is an advanced filter element (cartridge) used in Caterpillar (CAT) machines equipped with modern C4.4 and C6.6 series diesel engines. This product combines the function of fine fuel cleaning with water separation, which is essential for protecting injectors and high-pressure pumps in wheeled excavators, loaders, and dozers.
REDX filters with "Advanced Efficiency" technology offer a higher degree of filtration than standard cartridges. They trap the finest solid particles and effectively coalesce water, protecting the fuel system from erosion and corrosion.

Filter fits machines with C4.4 and C6.6 engines. Check cartridge dimensions: 166mm (height) / 94mm (outer diameter).
Filter 3087298 is a water separator element. It should be installed in the fuel filter housing. When replacing, we also recommend replacing the housing gasket (often included in the set) and checking the condition of the fine fuel filter.
Neglecting water separator replacement can lead to water entering the injection system. In C4.4/C6.6 engines, water causes immediate corrosion and seizure of expensive injectors and the Common Rail pump. Drain the sediment bowl regularly!
The filter is responsible for fuel pre-cleaning and water separation.

It means the filter has a denser media structure, capable of trapping smaller contaminant particles than standard filters, which is required for modern fuel systems.
This specific model is dedicated mainly to C4.4 and C6.6. Other filters are often used for C7.1, although there may be exceptions in some configurations. Always check the part number.
Cartridge type filters (elements) are more eco-friendly than spin-on filters because only the paper-plastic center is replaced, while the metal or plastic housing remains in the machine, generating less waste.
