The RW BECKETT F86-6 is an 8-micron oil filter cartridge supplied with a matching gasket and packaged for single-unit installation. This cartridge filters fuel oil ahead of the burner nozzle, protecting the nozzle assembly and fuel pump from particulate contamination. It is a standard service component in residential and light-commercial oil-fired heating systems and is installed by licensed oil burner technicians during routine annual tune-ups or as part of a no-heat service call. The included gasket eliminates the need to source a separate seal, keeping the canister closure leak-free after service.
This cartridge fits inline oil filter housings used on oil-fired furnaces, boilers, and water heaters. It is a direct-replacement service part intended for periodic replacement during scheduled oil burner maintenance. Technicians typically replace the cartridge each heating season to maintain clean fuel delivery and protect downstream components from sediment, water emulsion, and other fuel contaminants common in storage tanks.
Designed as an OEM-style replacement cartridge for oil filter canisters used in residential and light-commercial oil-fired heating systems. Confirm canister thread size and cartridge outside diameter against your housing before installation.
Oil burner filter cartridges are serviced by licensed oil burner technicians in accordance with applicable local and state codes. Before replacing the cartridge, shut off the fuel supply valve and allow the system to de-energize completely. Use an appropriate filter wrench to remove the canister bowl, drain residual oil safely, install the new cartridge and gasket, and torque the bowl hand-tight per the housing manufacturer's guidance. After reassembly, open the fuel valve, check for leaks at the canister seal, and bleed the fuel line as needed before firing the burner.
