Fuel Water Separator BF1357

The BF1357 Fuel Water Separator is a premium, high-capacity spin-on filtration element engineered to safeguard large-displacement diesel engines operating under punishing environmental conditions. Featuring advanced multi-layer melt-blown media, this element is purpose-built as a direct, high-performance replacement for Baldwin BF1357, Fleetguard FS19946, Donaldson P550937, and Mann Filter WK 13 003.

Engineered to match the rigorous fueling tolerances of heavy-duty Komatsu industrial engines (such as the SAA6D125E, SAA6D140E, and SAA6D170E series), the BF1357 acts as an essential defense barrier against moisture and fine particulates. In intense mining, earthmoving, and aggregate crushing environments, emulsified water and microscopic contaminants can cause severe fuel injector corrosion and fuel pump scuffing. The BF1357 achieves exceptional water separation efficiency and extensive dirt-holding capacity, catching water droplets and harmful abrasives before they reach the high-pressure fuel rail. Integrated with a durable spin-on design and a transparent collection bowl for immediate visual inspection, it significantly extends service intervals, ensures maximum fuel purity, and protects your heavy machinery from costly unexpected downtime.
