Baldwin Filters BF46122 Diesel Fuel Spin-On Filter

SKU CH-14JW-Z59F5

Diesel fuel spin-on filter with water separator drain and 0.001 micron rating

  • Spin-on design enables quick filter changes
  • Diesel fuel and water separation protects injection systems
  • 001 micron rating captures ultra-fine contaminants
  • Integrated drain simplifies water removal
  • Attached gasket ensures reliable seal on installation

Product Identity

The Baldwin Filters BF46122 is a new spin-on diesel fuel filter designed for machinery and machine shop applications. It functions as a fluid filter with an integrated fuel and water separator that includes a drain for removing collected water. The unit comes with an attached gasket and features a thread size of 1 In. -14 for installation.

Upgrade Context

This filter replaces a worn or clogged diesel fuel filter element to restore proper fuel and water separation performance. The jump is worth it when the existing unit can no longer achieve the rated 0.001 micron filtration level or when the drain function fails to remove water effectively. It is not for buyers who need a cartridge-style element or a filter without a water separation capability.

Build Integration

The spin-on design threads directly onto the compatible filter head using the 1 In. -14 threads, requiring no separate housing. The attached gasket seals the connection without additional parts. The can-type body measures 7 1/4 in height and 4 13/32 in outside diameter, so the mounting location must accommodate these dimensions. The unit carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Highlights

  • Spin-on design enables quick filter changes
  • Diesel fuel and water separation protects injection systems
  • 001 micron rating captures ultra-fine contaminants
  • Integrated drain simplifies water removal
  • Attached gasket ensures reliable seal on installation
