Baldwin BF9922-O Fuel Water Separator

The Baldwin BF9922-O is a spin-on fuel water separator cartridge designed to remove water and contaminants from fuel systems. It features an open port for a bowl connection and includes an integral post seal for reliable sealing. The cartridge uses a 1 In. -14 thread size for installation.

Suits engines needing spin-on water separation

This separator suits applications requiring a spin-on fuel water separator with a bowl connection for manual draining. It is not suited for systems requiring a closed-port cartridge without a bowl interface or those needing a different thread specification.

1 In. -14 thread size decides fitment

The 1 In. -14 thread size is the critical specification that determines compatibility with the filter head. Verify the thread requirement matches this specification exactly before purchase to ensure proper sealing and installation.

Questions about this item

How do I choose the right cartridge for my fuel system?

Select the BF9922-O when your housing requires a 4-1/8 in height and 1 in.-14 thread size; the open port accepts a 3-1/8 in.-10 thread bowl.

What does the 4-1/8 in length mean once installed?

That dimension is the overall cartridge height, so it determines the clearance needed above the mounting head in the engine compartment.

What does the 1 in.-14 thread cap in practice?

It sets the mating thread on the filter head; only heads cut to 1 in.-14 will seal correctly with the integral post seal and O-ring.
