Precision-sized #53 orifice controlling propane flow to the burner on compatible SF-25 series furnaces, helping maintain proper combustion.
The Suburban Mfg 180306 is a genuine OEM replacement furnace burner orifice, stamped #53, designed for select Suburban SF-25 series furnaces. The orifice precisely meters the amount of propane delivered to the burner, and installing the correct size is critical for proper combustion, flame quality, and safe furnace operation.
This orifice is sized specifically for the SF-25 series furnace, not a water heater. Suburban offers a range of similarly-numbered orifices in different sizes for other furnace models (for example, #55, #56, #60, #61, #65), so confirm the exact furnace model and required orifice size before ordering - installing the wrong size can affect combustion and furnace performance.
