Baldwin BF1252 Fuel Filter

The Baldwin BF1252 is a spin-on primary fuel and water separator designed for diesel fuel systems. It carries a 40 micron rating and uses a 1 in.-14 thread for installation. The filter includes an ES24-D furnished gasket and a G381-A integral gasket to seal the connection. Overall dimensions are 7 13/32 in height and length by 3 11/16 in width and outside diameter.

Who This Suits

Technicians maintaining heavy-duty diesel engines that specify a 40 micron primary separator with a 1 in.-14 thread will find this filter a direct fit. Fleets standardising on Baldwin filtration can use it for scheduled service intervals.

Who Should Look Elsewhere

Applications requiring a finer micron rating or a different thread size cannot use this filter. Systems that need a secondary filter element or a non-spin-on cartridge design are not compatible.

Capacity and Headroom

The 40 micron rating comfortably handles primary filtration duties, removing larger contaminants and separating water before fuel reaches the injection system. It runs out when the application demands tighter filtration or a different port configuration.

Questions about this item

What thread size must my fuel system have to fit this BF1252 spin-on filter?

The filter uses a 1 In. -14 thread, so your fuel head or adapter must match that exact thread specification for a proper seal.

Will the 40 micron rating of this BF1252 work with my existing secondary fuel filter?

Yes, a 40 micron primary separator is designed to remove water and large particles before fuel reaches a finer secondary filter downstream.

How can I confirm the BF1252 is sealed and draining correctly after installation?

Hand-tighten until the furnished ES24-D and integral G381-A gaskets seat, then check the drain valve for water discharge while the engine runs.
