Fleetguard Genuine Filters for Heavy-Duty Diesel Engines
Fleetguard is the filtration division of Cummins, which means the same engineers who design the engine also design the filters that protect it. For Cummins-powered trucks and equipment, as well as many Caterpillar and PACCAR applications, Fleetguard isn't simply compatible. It is the original specification.
Our Fleetguard collection focuses on the components that keep high-pressure common rail diesel systems running clean: fuel water separators, fuel filters, and crankcase ventilation filters built with Fleetguard's proprietary Stratapore and NanoNet media.
What You'll Find in This Collection
- Fuel water separators that remove 95% or more of free and emulsified water before it reaches your injectors
- NanoNet fuel filters rated to capture particles as small as 4 microns, protecting high-pressure pumps from premature wear
- Crankcase ventilation filters that manage blow-by and protect your turbocharger from oil contamination
- Bulk multi-packs designed for fleets and high-mileage drivers who want a lower cost per service
Why It Matters
Diesel fuel systems run at extremely high pressures with very tight tolerances, where even a small amount of unfiltered water or a few microns of debris can pit an injector tip or cause a high-pressure pump to fail. Fleetguard's multi-layer synthetic media is engineered to catch what standard paper filters miss, extending service life and protecting your investment in the engine.
