Baldwin BF1261 Spin-On Fuel Filter

The Baldwin BF1261 is a spin-on fuel filter that also works as a fuel and water separator with an integrated drain. It carries a 20 micron rating and uses an M16 x 1.50 thread size for installation. A G449-B integral gasket is furnished with the filter for a secure seal.

For diesel systems needing water separation

This filter suits diesel fuel systems that require both particle capture and water removal in a single spin-on housing. It is not intended for gasoline-only systems or for applications that demand a finer micron rating than 20 micron. Buyers who need a non-separator filter or a different thread pitch should look elsewhere.

20 micron rating with drain capacity

The 20 micron media handles typical diesel contaminants and the built-in drain lets operators purge collected water during routine service. Headroom ends when the filter reaches its holding limit or when service intervals call for a tighter micron specification not offered by this model.

Questions about this item

What thread size must my fuel line fitting have to accept the BF1261 spin-on filter?

The filter uses an M16 x 1.50 thread, so the mating fitting must match that pitch and diameter.

Will the BF1261 fit in the same housing as my older 20-micron filter that lacks a drain?

Yes, if the housing takes an M16 x 1.50 spin-on with a 3 in outside diameter and 4 7/32 in height, the BF1261 will mount directly.

How can I confirm the BF1261 is sealing and draining correctly after installation?

Pressurise the system, check the integral G449-B gasket for leaks, then open the drain valve — water and debris should exit cleanly.
