Fuel filter (water separator element) with part number 3608960 from the REDX offer. This is a key component of the fuel system in modern Caterpillar (CAT) machines equipped with C4.4, C7.1, and C3.4B ACERT series engines. This filter ensures final fuel purification before feeding it to the high-pressure pump, protecting sensitive Common Rail injectors from damage.
REDX filter cartridges are manufactured from multi-layer synthetic media that ensure micron-level filtration efficiency required for fuel systems meeting Tier 4 Final / Stage V emission standards.

Filter fits a huge range of modern CAT machines with C3.4B, C4.4, C6.6, C7.1 engines. Check dimensions: 155mm (height) / 82mm (outer diameter).
Filter 3608960 is a water separator element. It typically works with a fine fuel filter (e.g., 1R-0750 or 360-8960). Replace housing gaskets (usually included) with every cartridge change.
Modern injection systems are extremely sensitive to water and contamination. Using low-quality filters risks seizing the fuel pump and damaging injectors, the repair of which can cost thousands. Replace the cartridge regularly.
Filter 3608960 pre-cleans fuel and removes water.

It is a so-called pre-filter with water separator function. Its task is to retain the largest particles and separate water from the fuel before it reaches the pump.
It is usually mounted as the first in the fuel line from the tank, in an easily accessible place, often near the machine frame or in the engine compartment, so the operator can easily drain water from the sediment bowl.
In modern CAT engines, injection pressure can exceed 2000 bar. At this pressure, even a microscopic water droplet or dust particle acts like a bullet on the injector tip, causing material erosion.
