Fleetguard FS19594 Oil-Water Separator

Fleetguard FS19594 is a high-performance spin-on Oil-Water Separator engineered for diesel fuel systems, specialized in medium-duty commercial vehicles and industrial machinery powered by Cummins engines. Adopting Strata Pore filter media, it efficiently removes 20μm solid particulates and free/emulsified water from fuel, delivering clean fuel to core components and effectively preventing corrosion and wear of fuel injection systems.

This separator features a compact and optimized design, with an outer diameter of 76.71mm and an overall height of 141.71mm, paired with 3/4-16 UNF-2B threaded port. It perfectly fits the limited mounting space of medium-duty trucks and engineering machinery, enabling tool-free quick installation and replacement, and is fully compatible with Cummins C6003117480 and other mainstream engine models.

Compliant with SAE J1985 industry standards, FS19594 undergoes strict factory performance testing. It has no WIF sensor provision and maintains stable filtration performance under various complex working conditions, serving as a reliable OEM filtration part for medium-duty diesel equipment in transportation and industrial fields.

Advantages of  FS19594 Oil-Water Separator

  • Efficient filtration & water separation: It achieves 96% filtration efficiency for 20μm particulates and 90% separation efficiency for both free and emulsified water in fuel, thoroughly eliminating fuel contamination and reducing the failure risk of engine fuel systems.

  • Premium filter media performance: The proprietary Strata Pore media ensures high dirt-holding capacity and stable fuel flow rate, maintaining consistent filtration efficiency throughout the service life and lowering equipment maintenance frequency.

  • Excellent structural compatibility: With compact dimensional design and standard 3/4-16 UNF-2B threaded interface, it perfectly matches medium-duty Cummins engines and mainstream medium-duty commercial vehicles, realizing direct and quick replacement.

  • Reliable durability & adaptability: Constructed with high-strength metal canister and premium sealing gaskets, it resists vibration and pressure impact in harsh working environments, with no leakage risk and stable performance for long-term operation.
