Baldwin Filters BF1224 Fuel Filter

Baldwin BF1224 Fuel/Water Separator is a 4-1/4 in outside-diameter spin-on filter that provides simultaneous fuel filtration and water separation for diesel and other fuel systems. The BF1224 is the base model in Baldwin’s BF1224 family and is specified without a drain or sensor port, making it compatible with Baldwin spin-on bases that do not require those features. It uses a 1 in.-14 thread size for mounting and ships as a single filter with gasket, with packaging that typically lists 12 units per case. The BF1224 is widely stocked by major parts suppliers, including Grainger and NAPA, reflecting its role as a standard replacement filter in many fleets and refrigeration units; FleetPride notes its use in Carrier-Transicold refrigeration units, confirming a niche application where clean fuel and water separation protect equipment. When selecting a replacement, match the BF1224 to your base’s 4-1/4 in OD, 1 in.-14 thread, and absence of drain/sensor port to ensure a proper seal and easy installation. Cross-reference and multiple distributors help ensure availability and compatibility across a range of heavy-duty vehicles and Carrier refrigeration equipment.
