General Filters Inc 1A-25B Fuel Oil Filter 3/8 Inch Npt

Product Description

The GENERAL FILTERS INC 1A-25B is a fuel oil filter designed for use in oil-fired heating systems. It filters contaminants from fuel oil before it reaches the burner assembly, protecting downstream components such as the fuel pump, nozzle, and burner from debris-related wear and plugging. This filter uses biogaskets, which are compatible with biodiesel blends commonly found in today's heating fuel supply. It connects via a standard 3/8 inch NPT fitting, making it a straightforward drop-in replacement in most residential and light commercial oil heating systems. Installation is typically performed by oil heat technicians during routine service calls or at annual burner tune-ups.

This filter is suited for residential and light commercial oil-fired heating applications, including forced-air oil furnaces and oil boiler systems. The 3/8 inch NPT standard connection matches the typical inlet and outlet sizing found on most residential oil burner filter assemblies. The biogasket construction makes it appropriate for use with standard No. 2 fuel oil as well as biodiesel blends, addressing the growing use of bio-heating fuels in many markets.

Key Features

• Standard 3/8 inch NPT connection for broad compatibility with residential oil heating systems
• Biogaskets included for compatibility with biodiesel fuel blends
• Designed for installation in the oil supply line upstream of the burner assembly
• Sold as individual units with a package quantity of 12 per case

Compatibility

Installation Notes

Fuel oil filters are typically installed and serviced by licensed oil heat technicians. Before replacing the filter, shut off the oil supply valve and relieve any pressure in the line. Use appropriate thread sealant on NPT fittings and check for leaks after restoring fuel flow. Dispose of used filters and residual fuel oil in accordance with local environmental regulations.
