Baldwin BF1204-SP Spin-On Fuel Filter

The Baldwin BF1204-SP is a spin-on fuel filter designed as a secondary fuel and water separator for diesel fuel systems. It carries a 20 micron rating to capture fine contaminants while allowing adequate flow. The unit includes an integral gasket and post seal for reliable sealing. A 1/2-20 sensor port thread is provided for water-in-fuel monitoring.

Sustained Load Behaviour

Under continuous operation the filter separates water from fuel through the integral separator bowl and drain. The 20 micron media maintains consistent filtration efficiency as contaminant loading increases. The integral gasket and post seal retain their seal integrity through thermal cycles and vibration. The sensor port allows ongoing water level detection without interrupting flow.

Thread and Port Limits

The filter mounts via a 1 In. -14 thread size which dictates compatibility with existing filter heads. The 1/2-20 sensor port accepts only matching thread sensors for water detection. Physical dimensions of 6 1/16 in height and 3 11/16 in diameter define the installation envelope. The micron rating sets the lower particle size limit for captured debris.

Questions about this item

Does the 20 micron filter create noticeable fuel-flow restriction when the engine runs continuously?

The 20 micron rating is designed for secondary fuel filtration and maintains adequate flow for normal diesel operation without excessive pressure drop.

What thread size must the existing filter head have for this spin-on to seal correctly?

The filter uses a 1 In. -14 thread, so the filter head must match that thread specification for proper installation.

Will the integral post seal and gasket work with an older filter head that has a different sealing surface?

The integral gasket and post seal are engineered to seal against standard 1 In. -14 filter heads; mismatched surfaces may prevent a reliable seal.
