Baldwin Filters BF46023-O Fuel Filter Spin-On

The Baldwin Filters BF46023-O is a spin-on fuel filter designed for fuel and water separation in automotive and industrial systems. It features an open port for a collection bowl and includes a furnished gasket for a secure seal. This filter suits technicians and fleet operators maintaining diesel or gasoline fuel lines.

Upgrade from basic spin-on filters without water

Standard spin-on filters capture particulates but leave water in the fuel stream. The BF46023-O adds a separator bowl port so water can be drained before it reaches injectors. The jump is worth it when engines run in humid climates, sit for long periods, or draw from bulk tanks prone to condensation.

Handles 1-inch-14 thread systems

The filter fits housings using a 1-inch-14 thread and accepts bowls with a 1 1/4-10 thread. It covers common heavy-duty and commercial applications within those specifications. It does not fit metric-thread housings, smaller automotive threads, or systems requiring a closed-end canister without a bowl port.
