Filters are front-line protection for Cummins engine systems, removing contaminants from lubricating oil, fuel, coolant, air, and hydraulic circuits before they can cause wear or blockage. Cummins engines typically use spin-on or cartridge-type filters for oil and fuel, with panel or cylindrical elements for air filtration. Filter heads — the housings that mount the filter elements — contain bypass valves and sealing surfaces that must also be maintained. Regular filter replacement at the correct service intervals is one of the most cost-effective ways to protect engine components and extend service life.

While aftermarket filters exist, they may not meet Cummins filtration specifications for micron rating, flow capacity, or bypass valve cracking pressure. Genuine Cummins or Fleetguard filters are designed and tested to match the engine's filtration requirements.
The filter head is the mounting base for spin-on oil or fuel filters. It contains the filter bypass valve, sealing O-ring groove, and fluid passages. A damaged filter head can cause oil or fuel leaks, low pressure, or allow unfiltered fluid to bypass the filter element.
LF = Lube Filter (oil), FF = Fuel Filter, AF = Air Filter, HF = Hydraulic Filter, FS = Fuel/Water Separator. These are Fleetguard product codes used across Cummins filtration products.
