Cummins Fuel Filter 4328041 For QSK38

The Cummins Fuel Filter 4328041 is a state-of-the-art OEM component precision-engineered for QSK38 engines powering heavy-duty applications in mining, construction, and power generation. As the critical first defense in the fuel system, it ensures 99.98% removal of contaminants ≥2μm, delivering ultra-clean fuel to protect high-pressure injection systems from particle-induced failures.

1. Pre-Filtration Layer:

- 100μm stainless steel mesh traps rust flakes and coarse debris.

- Extends primary media lifespan by 40% versus single-stage designs.

2. Primary Media:

- High-density fiberglass/polymer blend with 2μm absolute rating.

- Pleated design increases surface area by 300% for 5,000-hour service life.

3. Final Polishing Layer:

- 5μm synthetic mesh captures residual particles, achieving 99.98% efficiency.
