The RW BECKETT 31653 is a replacement gasket designed for use with standard-flange oil burner assemblies. This gasket seats between the oil burner and the boiler or furnace flange, creating a combustion-tight seal that prevents flue gas leakage at the burner mounting point. It is a consumable service part replaced during routine burner maintenance, combustion tune-ups, or whenever the burner is dismounted from the appliance. Licensed oil heat technicians install this part as part of annual service procedures on residential and light-commercial heating systems. Proper sealing at the burner flange is essential for safe and efficient combustion performance.
This gasket is specified for use with several RW BECKETT oil burner models, including the AF, AFG, SR, SF, CF375, CF500, CF800, and NX series. These burners are commonly installed in residential oil-fired furnaces, boilers, and water heaters across the northeastern and mid-Atlantic United States, as well as in light-commercial heating applications. The 31653 is the correct OEM-style replacement for standard-flange burner configurations on these units, making it a stock item for oil heat service technicians.
Designed for use with RW BECKETT AF, AFG, SR, SF, CF375, CF500, CF800, and NX oil burner models with standard-flange mounting.
Installation must be performed by a qualified and licensed oil heat contractor using properly calibrated combustion test equipment. Before removing or remounting the burner, shut down the heating system and allow it to cool completely. Inspect the mating flange surface on the appliance for damage or buildup before seating the new gasket. After installation, perform a full combustion analysis to verify safe and proper burner operation in accordance with applicable local and NFPA codes.
