Generalaire 1A-25B Fuel Oil Filter 10 Micron 3/8 Inch Npt

Product Description

The GENERALAIRE 1A-25B is a fuel oil filter designed for use in residential and light commercial oil-fired heating systems. It features a 10-micron filter rating that captures particulates and debris before they reach the burner, helping protect fuel delivery components from contamination. The housing is constructed from epoxy coated galvanized steel for durability in fuel oil service environments. The unit uses a 3/8 inch NPT threaded end connection and is rated to 12 psi. A bonded center core prevents media migration, keeping filter media contained throughout the service cycle. Licensed oil burner technicians and heating service professionals perform this type of installation.

This filter is intended for use in fuel oil supply lines feeding residential and commercial oil burner systems. It is installed in the oil supply line between the storage tank and the burner unit, typically near the burner or oil pump. The 3/8 inch NPT port size is a common connection size found in standard residential oil heating systems. The 10-micron rating makes it appropriate for primary filtration duties where protecting downstream components such as fuel pumps and nozzles is the priority.
